+If the |SEARCH_XXX| is found the result is stored in the variable
+and the search will not be repeated unless the variable is cleared.

+add_custom_command
+------------------
+
+Add a custom build rule to the generated build system.
+
+There are two main signatures for add_custom_command The first
+signature is for adding a custom command to produce an output.
+
+::
+
+  add_custom_command(OUTPUT output1 [output2 ...]
+                     COMMAND command1 [ARGS] [args1...]
+                     [COMMAND command2 [ARGS] [args2...] ...]
+                     [MAIN_DEPENDENCY depend]
+                     [DEPENDS [depends...]]
+                     [IMPLICIT_DEPENDS <lang1> depend1
+                                      [<lang2> depend2] ...]
+                     [WORKING_DIRECTORY dir]
+                     [COMMENT comment] [VERBATIM] [APPEND])
+
+This defines a command to generate specified OUTPUT file(s).  A target
+created in the same directory (CMakeLists.txt file) that specifies any
+output of the custom command as a source file is given a rule to
+generate the file using the command at build time.  Do not list the
+output in more than one independent target that may build in parallel
+or the two instances of the rule may conflict (instead use
+add_custom_target to drive the command and make the other targets
+depend on that one).  If an output name is a relative path it will be
+interpreted relative to the build tree directory corresponding to the
+current source directory.  Note that MAIN_DEPENDENCY is completely
+optional and is used as a suggestion to visual studio about where to
+hang the custom command.  In makefile terms this creates a new target
+in the following form:
+
+::
+
+  OUTPUT: MAIN_DEPENDENCY DEPENDS
+          COMMAND
+
+If more than one command is specified they will be executed in order.
+The optional ARGS argument is for backward compatibility and will be
+ignored.
+
+The second signature adds a custom command to a target such as a
+library or executable.  This is useful for performing an operation
+before or after building the target.  The command becomes part of the
+target and will only execute when the target itself is built.  If the
+target is already built, the command will not execute.
+
+::
+
+  add_custom_command(TARGET target
+                     PRE_BUILD | PRE_LINK | POST_BUILD
+                     COMMAND command1 [ARGS] [args1...]
+                     [COMMAND command2 [ARGS] [args2...] ...]
+                     [WORKING_DIRECTORY dir]
+                     [COMMENT comment] [VERBATIM])
+
+This defines a new command that will be associated with building the
+specified target.  When the command will happen is determined by which
+of the following is specified:
+
+::
+
+  PRE_BUILD - run before all other dependencies
+  PRE_LINK - run after other dependencies
+  POST_BUILD - run after the target has been built
+
+Note that the PRE_BUILD option is only supported on Visual Studio 7 or
+later.  For all other generators PRE_BUILD will be treated as
+PRE_LINK.
+
+If WORKING_DIRECTORY is specified the command will be executed in the
+directory given.  If it is a relative path it will be interpreted
+relative to the build tree directory corresponding to the current
+source directory.  If COMMENT is set, the value will be displayed as a
+message before the commands are executed at build time.  If APPEND is
+specified the COMMAND and DEPENDS option values are appended to the
+custom command for the first output specified.  There must have
+already been a previous call to this command with the same output.
+The COMMENT, WORKING_DIRECTORY, and MAIN_DEPENDENCY options are
+currently ignored when APPEND is given, but may be used in the future.
+
+If VERBATIM is given then all arguments to the commands will be
+escaped properly for the build tool so that the invoked command
+receives each argument unchanged.  Note that one level of escapes is
+still used by the CMake language processor before add_custom_command
+even sees the arguments.  Use of VERBATIM is recommended as it enables
+correct behavior.  When VERBATIM is not given the behavior is platform
+specific because there is no protection of tool-specific special
+characters.
+
+If the output of the custom command is not actually created as a file
+on disk it should be marked as SYMBOLIC with
+SET_SOURCE_FILES_PROPERTIES.
+
+The IMPLICIT_DEPENDS option requests scanning of implicit dependencies
+of an input file.  The language given specifies the programming
+language whose corresponding dependency scanner should be used.
+Currently only C and CXX language scanners are supported.  The
+language has to be specified for every file in the IMPLICIT_DEPENDS
+list.  Dependencies discovered from the scanning are added to those of
+the custom command at build time.  Note that the IMPLICIT_DEPENDS
+option is currently supported only for Makefile generators and will be
+ignored by other generators.
+
+If COMMAND specifies an executable target (created by ADD_EXECUTABLE)
+it will automatically be replaced by the location of the executable
+created at build time.  Additionally a target-level dependency will be
+added so that the executable target will be built before any target
+using this custom command.  However this does NOT add a file-level
+dependency that would cause the custom command to re-run whenever the
+executable is recompiled.
+
+Arguments to COMMAND may use "generator expressions" with the syntax
+"$<...>".  See the :manual:`cmake-generator-expressions(7)` manual for
+available expressions.
+
+Note that tgt is not added as a dependency of the target this
+expression is evaluated on.
+
+::
+
+  $<TARGET_POLICY:pol>          = '1' if the policy was NEW when the 'head' target was created, else '0'.  If the policy was not set, the warning message for the policy will be emitted.  This generator expression only works for a subset of policies.
+  $<INSTALL_PREFIX>         = Content of the install prefix when the target is exported via INSTALL(EXPORT) and empty otherwise.
+
+Boolean expressions:
+
+::
+
+  $<AND:?[,?]...>           = '1' if all '?' are '1', else '0'
+  $<OR:?[,?]...>            = '0' if all '?' are '0', else '1'
+  $<NOT:?>                  = '0' if '?' is '1', else '1'
+
+where '?' is always either '0' or '1'.
+
+Expressions with an implicit 'this' target:
+
+::
+
+  $<TARGET_PROPERTY:prop>   = The value of the property prop on the target on which the generator expression is evaluated.
+
+References to target names in generator expressions imply target-level
+dependencies, but NOT file-level dependencies.  List target names with
+the DEPENDS option to add file dependencies.
+
+The DEPENDS option specifies files on which the command depends.  If
+any dependency is an OUTPUT of another custom command in the same
+directory (CMakeLists.txt file) CMake automatically brings the other
+custom command into the target in which this command is built.  If
+DEPENDS is not specified the command will run whenever the OUTPUT is
+missing; if the command does not actually create the OUTPUT then the
+rule will always run.  If DEPENDS specifies any target (created by an
+ADD_* command) a target-level dependency is created to make sure the
+target is built before any target using this custom command.
+Additionally, if the target is an executable or library a file-level
+dependency is created to cause the custom command to re-run whenever
+the target is recompiled.

+              [EXCLUDE_FROM_ALL]
+              source1 source2 ... sourceN)
+
+Adds a library target called <name> to be built from the source files
+listed in the command invocation.  The <name> corresponds to the
+logical target name and must be globally unique within a project.  The
+actual file name of the library built is constructed based on
+conventions of the native platform (such as lib<name>.a or
+<name>.lib).
+
+STATIC, SHARED, or MODULE may be given to specify the type of library
+to be created.  STATIC libraries are archives of object files for use
+when linking other targets.  SHARED libraries are linked dynamically
+and loaded at runtime.  MODULE libraries are plugins that are not
+linked into other targets but may be loaded dynamically at runtime
+using dlopen-like functionality.  If no type is given explicitly the
+type is STATIC or SHARED based on whether the current value of the
+variable BUILD_SHARED_LIBS is true.  For SHARED and MODULE libraries
+the POSITION_INDEPENDENT_CODE target property is set to TRUE
+automatically.
+
+By default the library file will be created in the build tree
+directory corresponding to the source tree directory in which the
+command was invoked.  See documentation of the
+ARCHIVE_OUTPUT_DIRECTORY, LIBRARY_OUTPUT_DIRECTORY, and
+RUNTIME_OUTPUT_DIRECTORY target properties to change this location.
+See documentation of the OUTPUT_NAME target property to change the
+<name> part of the final file name.
+
+If EXCLUDE_FROM_ALL is given the corresponding property will be set on
+the created target.  See documentation of the EXCLUDE_FROM_ALL target
+property for details.
+
+The add_library command can also create IMPORTED library targets using
+this signature:
+
+::
+
+  add_library(<name> <SHARED|STATIC|MODULE|UNKNOWN> IMPORTED
+              [GLOBAL])
+
+An IMPORTED library target references a library file located outside
+the project.  No rules are generated to build it.  The target name has
+scope in the directory in which it is created and below, but the
+GLOBAL option extends visibility.  It may be referenced like any
+target built within the project.  IMPORTED libraries are useful for
+convenient reference from commands like target_link_libraries.
+Details about the imported library are specified by setting properties
+whose names begin in ``IMPORTED_``.  The most important such property is
+IMPORTED_LOCATION (and its per-configuration version
+IMPORTED_LOCATION_<CONFIG>) which specifies the location of the main
+library file on disk.  See documentation of the IMPORTED_* properties
+for more information.
+
+The signature
+
+::
+
+  add_library(<name> OBJECT <src>...)
+
+creates a special "object library" target.  An object library compiles
+source files but does not archive or link their object files into a
+library.  Instead other targets created by add_library or
+add_executable may reference the objects using an expression of the
+form $<TARGET_OBJECTS:objlib> as a source, where "objlib" is the
+object library name.  For example:
+
+::
+
+  add_library(... $<TARGET_OBJECTS:objlib> ...)
+  add_executable(... $<TARGET_OBJECTS:objlib> ...)
+
+will include objlib's object files in a library and an executable
+along with those compiled from their own sources.  Object libraries
+may contain only sources (and headers) that compile to object files.
+They may contain custom commands generating such sources, but not
+PRE_BUILD, PRE_LINK, or POST_BUILD commands.  Object libraries cannot
+be imported, exported, installed, or linked.  Some native build
+systems may not like targets that have only object files, so consider
+adding at least one real source file to any target that references
+$<TARGET_OBJECTS:objlib>.

+
+The signature
+
+::
+
+  add_library(<name> INTERFACE)
+
+creates an interface target.  An interface target does not directly
+create build output, though it may have properties set on it and it
+may be installed, exported and imported.  Typically the INTERFACE_*
+properties are populated on the interface target using the
+set_property(), target_link_libraries(), target_include_directories()
+and target_compile_defintions() commands, and then it is used as an
+argument to target_link_libraries() like any other target.

+
+Add a subdirectory to the build.  The source_dir specifies the
+directory in which the source CMakeLists.txt and code files are
+located.  If it is a relative path it will be evaluated with respect
+to the current directory (the typical usage), but it may also be an

+place the output files.  If it is a relative path it will be evaluated
+with respect to the current output directory, but it may also be an
+absolute path.  If binary_dir is not specified, the value of
+source_dir, before expanding any relative path, will be used (the
+typical usage).  The CMakeLists.txt file in the specified source
+directory will be processed immediately by CMake before processing in
+the current input file continues beyond this command.
+
+If the EXCLUDE_FROM_ALL argument is provided then targets in the
+subdirectory will not be included in the ALL target of the parent
+directory by default, and will be excluded from IDE project files.
+Users must explicitly build targets in the subdirectory.  This is
+meant for use when the subdirectory contains a separate part of the
+project that is useful but not necessary, such as a set of examples.
+Typically the subdirectory should contain its own project() command
+invocation so that a full build system will be generated in the
+subdirectory (such as a VS IDE solution file).  Note that inter-target
+dependencies supercede this exclusion.  If a target built by the
+parent project depends on a target in the subdirectory, the dependee
+target will be included in the parent project build system to satisfy
+the dependency.

+cmake_policy
+------------
+
+Manage CMake Policy settings.
+
+As CMake evolves it is sometimes necessary to change existing behavior
+in order to fix bugs or improve implementations of existing features.
+The CMake Policy mechanism is designed to help keep existing projects
+building as new versions of CMake introduce changes in behavior.  Each
+new policy (behavioral change) is given an identifier of the form
+"CMP<NNNN>" where "<NNNN>" is an integer index.  Documentation
+associated with each policy describes the OLD and NEW behavior and the
+reason the policy was introduced.  Projects may set each policy to
+select the desired behavior.  When CMake needs to know which behavior
+to use it checks for a setting specified by the project.  If no
+setting is available the OLD behavior is assumed and a warning is
+produced requesting that the policy be set.
+
+The cmake_policy command is used to set policies to OLD or NEW
+behavior.  While setting policies individually is supported, we
+encourage projects to set policies based on CMake versions.
+
+::
+
+  cmake_policy(VERSION major.minor[.patch[.tweak]])
+
+Specify that the current CMake list file is written for the given
+version of CMake.  All policies introduced in the specified version or
+earlier will be set to use NEW behavior.  All policies introduced
+after the specified version will be unset (unless variable
+CMAKE_POLICY_DEFAULT_CMP<NNNN> sets a default).  This effectively
+requests behavior preferred as of a given CMake version and tells
+newer CMake versions to warn about their new policies.  The policy
+version specified must be at least 2.4 or the command will report an
+error.  In order to get compatibility features supporting versions
+earlier than 2.4 see documentation of policy CMP0001.
+
+::
+
+  cmake_policy(SET CMP<NNNN> NEW)
+  cmake_policy(SET CMP<NNNN> OLD)
+
+Tell CMake to use the OLD or NEW behavior for a given policy.
+Projects depending on the old behavior of a given policy may silence a
+policy warning by setting the policy state to OLD.  Alternatively one
+may fix the project to work with the new behavior and set the policy
+state to NEW.
+
+::
+
+  cmake_policy(GET CMP<NNNN> <variable>)
+
+Check whether a given policy is set to OLD or NEW behavior.  The
+output variable value will be "OLD" or "NEW" if the policy is set, and
+empty otherwise.
+
+CMake keeps policy settings on a stack, so changes made by the
+cmake_policy command affect only the top of the stack.  A new entry on
+the policy stack is managed automatically for each subdirectory to
+protect its parents and siblings.  CMake also manages a new entry for
+scripts loaded by include() and find_package() commands except when
+invoked with the NO_POLICY_SCOPE option (see also policy CMP0011).
+The cmake_policy command provides an interface to manage custom
+entries on the policy stack:
+
+::
+
+  cmake_policy(PUSH)
+  cmake_policy(POP)
+
+Each PUSH must have a matching POP to erase any changes.  This is
+useful to make temporary changes to policy settings.
+
+Functions and macros record policy settings when they are created and
+use the pre-record policies when they are invoked.  If the function or
+macro implementation sets policies, the changes automatically
+propagate up through callers until they reach the closest nested
+policy stack entry.

+does not exist.  (If the file is a build input, use configure_file to
+update the file only when its content changes.)
+
+APPEND will write a message into a file same as WRITE, except it will

+
+MD5, SHA1, SHA224, SHA256, SHA384, and SHA512 will compute a

+
+STRINGS will parse a list of ASCII strings from a file and store it in
+a variable.  Binary data in the file are ignored.  Carriage return
+(CR) characters are ignored.  It works also for Intel Hex and Motorola
+S-record files, which are automatically converted to binary format

+
+LIMIT_COUNT sets the maximum number of strings to return.  LIMIT_INPUT
+sets the maximum number of bytes to read from the input file.
+LIMIT_OUTPUT sets the maximum number of bytes to store in the output
+variable.  LENGTH_MINIMUM sets the minimum length of a string to
+return.  Shorter strings are ignored.  LENGTH_MAXIMUM sets the maximum
+length of a string to return.  Longer strings are split into strings
+no longer than the maximum length.  NEWLINE_CONSUME allows newlines to
+be included in strings instead of terminating them.
+
+REGEX specifies a regular expression that a string must match to be
+returned.  Typical usage
+
+::
+
+  file(STRINGS myfile.txt myfile)
+
+stores a list in the variable "myfile" in which each item is a line
+from the input file.
+
+GLOB will generate a list of all files that match the globbing
+expressions and store it into the variable.  Globbing expressions are
+similar to regular expressions, but much simpler.  If RELATIVE flag is
+specified for an expression, the results will be returned as a
+relative path to the given path.  (We do not recommend using GLOB to
+collect a list of source files from your source tree.  If no
+CMakeLists.txt file changes when a source is added or removed then the
+generated build system cannot know when to ask CMake to regenerate.)
+
+Examples of globbing expressions include:
+
+::
+
+   *.cxx      - match all files with extension cxx
+   *.vt?      - match all files with extension vta,...,vtz
+   f[3-5].txt - match files f3.txt, f4.txt, f5.txt
+
+GLOB_RECURSE will generate a list similar to the regular GLOB, except
+it will traverse all the subdirectories of the matched directory and
+match the files.  Subdirectories that are symlinks are only traversed
+if FOLLOW_SYMLINKS is given or cmake policy CMP0009 is not set to NEW.
+See cmake --help-policy CMP0009 for more information.
+
+Examples of recursive globbing include:
+
+::
+
+   /dir/*.py  - match all python files in /dir and subdirectories
+
+MAKE_DIRECTORY will create the given directories, also if their parent
+directories don't exist yet
+
+RENAME moves a file or directory within a filesystem, replacing the
+destination atomically.
+
+REMOVE will remove the given files, also in subdirectories
+
+REMOVE_RECURSE will remove the given files and directories, also
+non-empty directories
+
+RELATIVE_PATH will determine relative path from directory to the given
+file.
+
+TO_CMAKE_PATH will convert path into a cmake style path with unix /.
+The input can be a single path or a system path like "$ENV{PATH}".
+Note the double quotes around the ENV call TO_CMAKE_PATH only takes
+one argument.  This command will also convert the native list
+delimiters for a list of paths like the PATH environment variable.
+
+TO_NATIVE_PATH works just like TO_CMAKE_PATH, but will convert from a
+cmake style path into the native path style \ for windows and / for
+UNIX.
+
+DOWNLOAD will download the given URL to the given file.  If LOG var is
+specified a log of the download will be put in var.  If STATUS var is
+specified the status of the operation will be put in var.  The status
+is returned in a list of length 2.  The first element is the numeric
+return value for the operation, and the second element is a string
+value for the error.  A 0 numeric error means no error in the
+operation.  If TIMEOUT time is specified, the operation will timeout
+after time seconds, time should be specified as an integer.  The
+INACTIVITY_TIMEOUT specifies an integer number of seconds of
+inactivity after which the operation should terminate.  If
+EXPECTED_HASH ALGO=value is specified, the operation will verify that
+the downloaded file's actual hash matches the expected value, where
+ALGO is one of MD5, SHA1, SHA224, SHA256, SHA384, or SHA512.  If it
+does not match, the operation fails with an error.  ("EXPECTED_MD5
+sum" is short-hand for "EXPECTED_HASH MD5=sum".) If SHOW_PROGRESS is
+specified, progress information will be printed as status messages
+until the operation is complete.  For https URLs CMake must be built
+with OpenSSL.  TLS/SSL certificates are not checked by default.  Set
+TLS_VERIFY to ON to check certificates and/or use EXPECTED_HASH to
+verify downloaded content.  Set TLS_CAINFO to specify a custom
+Certificate Authority file.  If either TLS option is not given CMake

+
+The COPY signature copies files, directories, and symlinks to a
+destination folder.  Relative input paths are evaluated with respect
+to the current source directory, and a relative destination is
+evaluated with respect to the current build directory.  Copying
+preserves input file timestamps, and optimizes out a file if it exists
+at the destination with the same timestamp.  Copying preserves input
+permissions unless explicit permissions or NO_SOURCE_PERMISSIONS are
+given (default is USE_SOURCE_PERMISSIONS).  See the install(DIRECTORY)
+command for documentation of permissions, PATTERN, REGEX, and EXCLUDE
+options.
+
+The INSTALL signature differs slightly from COPY: it prints status
+messages, and NO_SOURCE_PERMISSIONS is default.  Installation scripts
+generated by the install() command use this signature (with some
+undocumented options for internal use).
+
+GENERATE will write an <output_file> with content from an
+<input_file>, or from <input_content>.  The output is generated
+conditionally based on the content of the <condition>.  The file is
+written at CMake generate-time and the input may contain generator
+expressions.  The <condition>, <output_file> and <input_file> may also
+contain generator expressions.  The <condition> must evaluate to
+either '0' or '1'.  The <output_file> must evaluate to a unique name
+among all configurations and among all invocations of file(GENERATE).

+               [NO_POLICY_SCOPE])
+
+Finds and loads settings from an external project.  <package>_FOUND
+will be set to indicate whether the package was found.  When the
+package is found package-specific information is provided through
+variables and imported targets documented by the package itself.  The
+QUIET option disables messages if the package cannot be found.  The
+MODULE option disables the second signature documented below.  The
+REQUIRED option stops processing with an error message if the package
+cannot be found.
+
+A package-specific list of required components may be listed after the
+COMPONENTS option (or after the REQUIRED option if present).
+Additional optional components may be listed after
+OPTIONAL_COMPONENTS.  Available components and their influence on
+whether a package is considered to be found are defined by the target
+package.
+
+The [version] argument requests a version with which the package found
+should be compatible (format is major[.minor[.patch[.tweak]]]).  The
+EXACT option requests that the version be matched exactly.  If no
+[version] and/or component list is given to a recursive invocation
+inside a find-module, the corresponding arguments are forwarded
+automatically from the outer call (including the EXACT flag for
+[version]).  Version support is currently provided only on a
+package-by-package basis (details below).
+
+User code should generally look for packages using the above simple
+signature.  The remainder of this command documentation specifies the
+full command signature and details of the search process.  Project
+maintainers wishing to provide a package to be found by this command
+are encouraged to read on.
+
+The command has two modes by which it searches for packages: "Module"
+mode and "Config" mode.  Module mode is available when the command is
+invoked with the above reduced signature.  CMake searches for a file
+called "Find<package>.cmake" in the CMAKE_MODULE_PATH followed by the
+CMake installation.  If the file is found, it is read and processed by
+CMake.  It is responsible for finding the package, checking the
+version, and producing any needed messages.  Many find-modules provide
+limited or no support for versioning; check the module documentation.
+If no module is found and the MODULE option is not given the command
+proceeds to Config mode.
+
+The complete Config mode command signature is:
+
+::
+
+  find_package(<package> [version] [EXACT] [QUIET]
+               [REQUIRED] [[COMPONENTS] [components...]]
+               [CONFIG|NO_MODULE]
+               [NO_POLICY_SCOPE]
+               [NAMES name1 [name2 ...]]
+               [CONFIGS config1 [config2 ...]]
+               [HINTS path1 [path2 ... ]]
+               [PATHS path1 [path2 ... ]]
+               [PATH_SUFFIXES suffix1 [suffix2 ...]]
+               [NO_DEFAULT_PATH]
+               [NO_CMAKE_ENVIRONMENT_PATH]
+               [NO_CMAKE_PATH]
+               [NO_SYSTEM_ENVIRONMENT_PATH]
+               [NO_CMAKE_PACKAGE_REGISTRY]
+               [NO_CMAKE_BUILDS_PATH]
+               [NO_CMAKE_SYSTEM_PATH]
+               [NO_CMAKE_SYSTEM_PACKAGE_REGISTRY]
+               [CMAKE_FIND_ROOT_PATH_BOTH |
+                ONLY_CMAKE_FIND_ROOT_PATH |
+                NO_CMAKE_FIND_ROOT_PATH])
+
+The CONFIG option may be used to skip Module mode explicitly and
+switch to Config mode.  It is synonymous to using NO_MODULE.  Config
+mode is also implied by use of options not specified in the reduced
+signature.
+
+Config mode attempts to locate a configuration file provided by the
+package to be found.  A cache entry called <package>_DIR is created to
+hold the directory containing the file.  By default the command
+searches for a package with the name <package>.  If the NAMES option
+is given the names following it are used instead of <package>.  The
+command searches for a file called "<name>Config.cmake" or
+"<lower-case-name>-config.cmake" for each name specified.  A
+replacement set of possible configuration file names may be given
+using the CONFIGS option.  The search procedure is specified below.
+Once found, the configuration file is read and processed by CMake.
+Since the file is provided by the package it already knows the
+location of package contents.  The full path to the configuration file
+is stored in the cmake variable <package>_CONFIG.
+
+All configuration files which have been considered by CMake while
+searching for an installation of the package with an appropriate
+version are stored in the cmake variable <package>_CONSIDERED_CONFIGS,
+the associated versions in <package>_CONSIDERED_VERSIONS.
+
+If the package configuration file cannot be found CMake will generate
+an error describing the problem unless the QUIET argument is
+specified.  If REQUIRED is specified and the package is not found a
+fatal error is generated and the configure step stops executing.  If
+<package>_DIR has been set to a directory not containing a
+configuration file CMake will ignore it and search from scratch.
+
+When the [version] argument is given Config mode will only find a
+version of the package that claims compatibility with the requested
+version (format is major[.minor[.patch[.tweak]]]).  If the EXACT
+option is given only a version of the package claiming an exact match
+of the requested version may be found.  CMake does not establish any
+convention for the meaning of version numbers.  Package version
+numbers are checked by "version" files provided by the packages
+themselves.  For a candidate package configuration file
+"<config-file>.cmake" the corresponding version file is located next
+to it and named either "<config-file>-version.cmake" or
+"<config-file>Version.cmake".  If no such version file is available
+then the configuration file is assumed to not be compatible with any
+requested version.  A basic version file containing generic version
+matching code can be created using the macro
+write_basic_package_version_file(), see its documentation for more
+details.  When a version file is found it is loaded to check the
+requested version number.  The version file is loaded in a nested
+scope in which the following variables have been defined:
+
+::
+
+  PACKAGE_FIND_NAME          = the <package> name
+  PACKAGE_FIND_VERSION       = full requested version string
+  PACKAGE_FIND_VERSION_MAJOR = major version if requested, else 0
+  PACKAGE_FIND_VERSION_MINOR = minor version if requested, else 0
+  PACKAGE_FIND_VERSION_PATCH = patch version if requested, else 0
+  PACKAGE_FIND_VERSION_TWEAK = tweak version if requested, else 0
+  PACKAGE_FIND_VERSION_COUNT = number of version components, 0 to 4
+
+The version file checks whether it satisfies the requested version and
+sets these variables:
+
+::
+
+  PACKAGE_VERSION            = full provided version string
+  PACKAGE_VERSION_EXACT      = true if version is exact match
+  PACKAGE_VERSION_COMPATIBLE = true if version is compatible
+  PACKAGE_VERSION_UNSUITABLE = true if unsuitable as any version
+
+These variables are checked by the find_package command to determine
+whether the configuration file provides an acceptable version.  They
+are not available after the find_package call returns.  If the version
+is acceptable the following variables are set:
+
+::
+
+  <package>_VERSION       = full provided version string
+  <package>_VERSION_MAJOR = major version if provided, else 0
+  <package>_VERSION_MINOR = minor version if provided, else 0
+  <package>_VERSION_PATCH = patch version if provided, else 0
+  <package>_VERSION_TWEAK = tweak version if provided, else 0
+  <package>_VERSION_COUNT = number of version components, 0 to 4
+
+and the corresponding package configuration file is loaded.  When
+multiple package configuration files are available whose version files
+claim compatibility with the version requested it is unspecified which
+one is chosen.  No attempt is made to choose a highest or closest
+version number.
+
+Config mode provides an elaborate interface and search procedure.
+Much of the interface is provided for completeness and for use
+internally by find-modules loaded by Module mode.  Most user code
+should simply call
+
+::
+
+  find_package(<package> [major[.minor]] [EXACT] [REQUIRED|QUIET])
+
+in order to find a package.  Package maintainers providing CMake
+package configuration files are encouraged to name and install them
+such that the procedure outlined below will find them without
+requiring use of additional options.
+
+CMake constructs a set of possible installation prefixes for the
+package.  Under each prefix several directories are searched for a
+configuration file.  The tables below show the directories searched.
+Each entry is meant for installation trees following Windows (W), UNIX
+(U), or Apple (A) conventions.
+
+::
+
+  <prefix>/                                               (W)
+  <prefix>/(cmake|CMake)/                                 (W)
+  <prefix>/<name>*/                                       (W)
+  <prefix>/<name>*/(cmake|CMake)/                         (W)
+  <prefix>/(lib/<arch>|lib|share)/cmake/<name>*/          (U)
+  <prefix>/(lib/<arch>|lib|share)/<name>*/                (U)
+  <prefix>/(lib/<arch>|lib|share)/<name>*/(cmake|CMake)/  (U)
+
+On systems supporting OS X Frameworks and Application Bundles the
+following directories are searched for frameworks or bundles
+containing a configuration file:
+
+::
+
+  <prefix>/<name>.framework/Resources/                    (A)
+  <prefix>/<name>.framework/Resources/CMake/              (A)
+  <prefix>/<name>.framework/Versions/*/Resources/         (A)
+  <prefix>/<name>.framework/Versions/*/Resources/CMake/   (A)
+  <prefix>/<name>.app/Contents/Resources/                 (A)
+  <prefix>/<name>.app/Contents/Resources/CMake/           (A)
+
+In all cases the <name> is treated as case-insensitive and corresponds
+to any of the names specified (<package> or names given by NAMES).
+Paths with lib/<arch> are enabled if CMAKE_LIBRARY_ARCHITECTURE is
+set.  If PATH_SUFFIXES is specified the suffixes are appended to each
+(W) or (U) directory entry one-by-one.
+
+This set of directories is intended to work in cooperation with
+projects that provide configuration files in their installation trees.
+Directories above marked with (W) are intended for installations on
+Windows where the prefix may point at the top of an application's
+installation directory.  Those marked with (U) are intended for
+installations on UNIX platforms where the prefix is shared by multiple
+packages.  This is merely a convention, so all (W) and (U) directories
+are still searched on all platforms.  Directories marked with (A) are
+intended for installations on Apple platforms.  The cmake variables
+CMAKE_FIND_FRAMEWORK and CMAKE_FIND_APPBUNDLE determine the order of
+preference as specified below.
+
+The set of installation prefixes is constructed using the following
+steps.  If NO_DEFAULT_PATH is specified all NO_* options are enabled.
+
+1.  Search paths specified in cmake-specific cache variables.  These
+are intended to be used on the command line with a -DVAR=value.  This
+can be skipped if NO_CMAKE_PATH is passed.
+
+::
+
+   CMAKE_PREFIX_PATH
+   CMAKE_FRAMEWORK_PATH
+   CMAKE_APPBUNDLE_PATH
+
+2.  Search paths specified in cmake-specific environment variables.
+These are intended to be set in the user's shell configuration.  This
+can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
+
+::
+
+   <package>_DIR
+   CMAKE_PREFIX_PATH
+   CMAKE_FRAMEWORK_PATH
+   CMAKE_APPBUNDLE_PATH
+
+3.  Search paths specified by the HINTS option.  These should be paths
+computed by system introspection, such as a hint provided by the
+location of another item already found.  Hard-coded guesses should be
+specified with the PATHS option.
+
+4.  Search the standard system environment variables.  This can be
+skipped if NO_SYSTEM_ENVIRONMENT_PATH is passed.  Path entries ending
+in "/bin" or "/sbin" are automatically converted to their parent
+directories.
+
+::
+
+   PATH
+
+5.  Search project build trees recently configured in a CMake GUI.
+This can be skipped if NO_CMAKE_BUILDS_PATH is passed.  It is intended
+for the case when a user is building multiple dependent projects one
+after another.
+
+6.  Search paths stored in the CMake user package registry.  This can
+be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed.  On Windows a
+<package> may appear under registry key
+
+::
+
+  HKEY_CURRENT_USER\Software\Kitware\CMake\Packages\<package>
+
+as a REG_SZ value, with arbitrary name, that specifies the directory
+containing the package configuration file.  On UNIX platforms a
+<package> may appear under the directory
+
+::
+
+  ~/.cmake/packages/<package>
+
+as a file, with arbitrary name, whose content specifies the directory
+containing the package configuration file.  See the export(PACKAGE)
+command to create user package registry entries for project build
+trees.
+
+7.  Search cmake variables defined in the Platform files for the
+current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH is
+passed.
+
+::
+
+   CMAKE_SYSTEM_PREFIX_PATH
+   CMAKE_SYSTEM_FRAMEWORK_PATH
+   CMAKE_SYSTEM_APPBUNDLE_PATH
+
+8.  Search paths stored in the CMake system package registry.  This
+can be skipped if NO_CMAKE_SYSTEM_PACKAGE_REGISTRY is passed.  On
+Windows a <package> may appear under registry key
+
+::
+
+  HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<package>
+
+as a REG_SZ value, with arbitrary name, that specifies the directory
+containing the package configuration file.  There is no system package
+registry on non-Windows platforms.
+
+9.  Search paths specified by the PATHS option.  These are typically
+hard-coded guesses.

+ <package>_FIND_REQUIRED_<c>  = true if component <c> is required
+                                false if component <c> is optional
+
+In Module mode the loaded find module is responsible to honor the
+request detailed by these variables; see the find module for details.
+In Config mode find_package handles REQUIRED, QUIET, and version
+options automatically but leaves it to the package configuration file
+to handle components in a way that makes sense for the package.  The
+package configuration file may set <package>_FOUND to false to tell
+find_package that component requirements are not satisfied.

+arg3 (...).  Commands listed after function, but before the matching
+endfunction, are not invoked until the function is invoked.  When it
+is invoked, the commands recorded in the function are first modified
+by replacing formal parameters (${arg1}) with the arguments passed,
+and then invoked as normal commands.  In addition to referencing the
+formal parameters you can reference the variable ARGC which will be
+set to the number of arguments passed into the function as well as
+ARGV0 ARGV1 ARGV2 ...  which will have the actual values of the
+arguments passed in.  This facilitates creating functions with
+optional arguments.  Additionally ARGV holds the list of all arguments
+given to the function and ARGN holds the list of arguments past the
+last expected argument.
+
+A function opens a new scope: see set(var PARENT_SCOPE) for details.

+The expressions inside the parenthesis are evaluated first and then

+Where there are nested parenthesis the innermost are evaluated as part
+of evaluating the expression that contains them.
+
+The if command was written very early in CMake's history, predating
+the ${} variable evaluation syntax, and for convenience evaluates
+variables named by its arguments as shown in the above signatures.
+Note that normal variable evaluation with ${} applies before the if
+command even receives the arguments.  Therefore code like
+
+::
+
+  set(var1 OFF)
+  set(var2 "var1")
+  if(${var2})
+
+appears to the if command as
+
+::
+
+  if(var1)
+
+and is evaluated according to the if(<variable>) case documented
+above.  The result is OFF which is false.  However, if we remove the
+${} from the example then the command sees
+
+::
+
+  if(var2)
+
+which is true because var2 is defined to "var1" which is not a false
+constant.
+
+Automatic evaluation applies in the other cases whenever the
+above-documented signature accepts <variable|string>:
+
+1) The left hand argument to MATCHES is first checked to see if it is
+a defined variable, if so the variable's value is used, otherwise the
+original value is used.
+
+2) If the left hand argument to MATCHES is missing it returns false
+without error
+
+3) Both left and right hand arguments to LESS GREATER EQUAL are
+independently tested to see if they are defined variables, if so their
+defined values are used otherwise the original value is used.
+
+4) Both left and right hand arguments to STRLESS STREQUAL STRGREATER
+are independently tested to see if they are defined variables, if so
+their defined values are used otherwise the original value is used.
+
+5) Both left and right hand argumemnts to VERSION_LESS VERSION_EQUAL
+VERSION_GREATER are independently tested to see if they are defined
+variables, if so their defined values are used otherwise the original
+value is used.
+
+6) The right hand argument to NOT is tested to see if it is a boolean
+constant, if so the value is used, otherwise it is assumed to be a
+variable and it is dereferenced.
+
+7) The left and right hand arguments to AND OR are independently

+install
+-------
+
+Specify rules to run at install time.
+
+This command generates installation rules for a project.  Rules
+specified by calls to this command within a source directory are
+executed in order during installation.  The order across directories
+is not defined.
+
+There are multiple signatures for this command.  Some of them define
+installation properties for files and targets.  Properties common to
+multiple signatures are covered here but they are valid only for
+signatures that specify them.
+
+DESTINATION arguments specify the directory on disk to which a file
+will be installed.  If a full path (with a leading slash or drive
+letter) is given it is used directly.  If a relative path is given it
+is interpreted relative to the value of CMAKE_INSTALL_PREFIX.  The
+prefix can be relocated at install time using DESTDIR mechanism
+explained in the CMAKE_INSTALL_PREFIX variable documentation.
+
+PERMISSIONS arguments specify permissions for installed files.  Valid
+permissions are OWNER_READ, OWNER_WRITE, OWNER_EXECUTE, GROUP_READ,
+GROUP_WRITE, GROUP_EXECUTE, WORLD_READ, WORLD_WRITE, WORLD_EXECUTE,
+SETUID, and SETGID.  Permissions that do not make sense on certain
+platforms are ignored on those platforms.
+
+The CONFIGURATIONS argument specifies a list of build configurations
+for which the install rule applies (Debug, Release, etc.).
+
+The COMPONENT argument specifies an installation component name with
+which the install rule is associated, such as "runtime" or
+"development".  During component-specific installation only install
+rules associated with the given component name will be executed.
+During a full installation all components are installed.  If COMPONENT
+is not provided a default component "Unspecified" is created.  The
+default component name may be controlled with the
+CMAKE_INSTALL_DEFAULT_COMPONENT_NAME variable.
+
+The RENAME argument specifies a name for an installed file that may be
+different from the original file.  Renaming is allowed only when a
+single file is installed by the command.
+
+The OPTIONAL argument specifies that it is not an error if the file to
+be installed does not exist.
+
+The TARGETS signature:
+
+::
+
+  install(TARGETS targets... [EXPORT <export-name>]
+          [[ARCHIVE|LIBRARY|RUNTIME|FRAMEWORK|BUNDLE|
+            PRIVATE_HEADER|PUBLIC_HEADER|RESOURCE]
+           [DESTINATION <dir>]
+           [INCLUDES DESTINATION [<dir> ...]]
+           [PERMISSIONS permissions...]
+           [CONFIGURATIONS [Debug|Release|...]]
+           [COMPONENT <component>]
+           [OPTIONAL] [NAMELINK_ONLY|NAMELINK_SKIP]
+          ] [...])
+
+The TARGETS form specifies rules for installing targets from a
+project.  There are five kinds of target files that may be installed:
+ARCHIVE, LIBRARY, RUNTIME, FRAMEWORK, and BUNDLE.  Executables are
+treated as RUNTIME targets, except that those marked with the
+MACOSX_BUNDLE property are treated as BUNDLE targets on OS X.  Static
+libraries are always treated as ARCHIVE targets.  Module libraries are
+always treated as LIBRARY targets.  For non-DLL platforms shared
+libraries are treated as LIBRARY targets, except that those marked
+with the FRAMEWORK property are treated as FRAMEWORK targets on OS X.
+For DLL platforms the DLL part of a shared library is treated as a
+RUNTIME target and the corresponding import library is treated as an
+ARCHIVE target.  All Windows-based systems including Cygwin are DLL
+platforms.  The ARCHIVE, LIBRARY, RUNTIME, and FRAMEWORK arguments
+change the type of target to which the subsequent properties apply.
+If none is given the installation properties apply to all target
+types.  If only one is given then only targets of that type will be
+installed (which can be used to install just a DLL or just an import
+library).The INCLUDES DESTINATION specifies a list of directories
+which will be added to the INTERFACE_INCLUDE_DIRECTORIES of the
+<targets> when exported by install(EXPORT).  If a relative path is
+specified, it is treated as relative to the $<INSTALL_PREFIX>.
+
+The PRIVATE_HEADER, PUBLIC_HEADER, and RESOURCE arguments cause
+subsequent properties to be applied to installing a FRAMEWORK shared
+library target's associated files on non-Apple platforms.  Rules
+defined by these arguments are ignored on Apple platforms because the
+associated files are installed into the appropriate locations inside
+the framework folder.  See documentation of the PRIVATE_HEADER,
+PUBLIC_HEADER, and RESOURCE target properties for details.
+
+Either NAMELINK_ONLY or NAMELINK_SKIP may be specified as a LIBRARY
+option.  On some platforms a versioned shared library has a symbolic
+link such as
+
+::
+
+  lib<name>.so -> lib<name>.so.1
+
+where "lib<name>.so.1" is the soname of the library and "lib<name>.so"
+is a "namelink" allowing linkers to find the library when given
+"-l<name>".  The NAMELINK_ONLY option causes installation of only the
+namelink when a library target is installed.  The NAMELINK_SKIP option
+causes installation of library files other than the namelink when a
+library target is installed.  When neither option is given both
+portions are installed.  On platforms where versioned shared libraries
+do not have namelinks or when a library is not versioned the
+NAMELINK_SKIP option installs the library and the NAMELINK_ONLY option
+installs nothing.  See the VERSION and SOVERSION target properties for
+details on creating versioned shared libraries.
+
+One or more groups of properties may be specified in a single call to
+the TARGETS form of this command.  A target may be installed more than
+once to different locations.  Consider hypothetical targets "myExe",
+"mySharedLib", and "myStaticLib".  The code
+
+::
+
+    install(TARGETS myExe mySharedLib myStaticLib
+            RUNTIME DESTINATION bin
+            LIBRARY DESTINATION lib
+            ARCHIVE DESTINATION lib/static)
+    install(TARGETS mySharedLib DESTINATION /some/full/path)
+
+will install myExe to <prefix>/bin and myStaticLib to
+<prefix>/lib/static.  On non-DLL platforms mySharedLib will be
+installed to <prefix>/lib and /some/full/path.  On DLL platforms the
+mySharedLib DLL will be installed to <prefix>/bin and /some/full/path
+and its import library will be installed to <prefix>/lib/static and
+/some/full/path.
+
+The EXPORT option associates the installed target files with an export
+called <export-name>.  It must appear before any RUNTIME, LIBRARY, or
+ARCHIVE options.  To actually install the export file itself, call
+install(EXPORT).  See documentation of the install(EXPORT ...)
+signature below for details.
+
+Installing a target with EXCLUDE_FROM_ALL set to true has undefined
+behavior.
+
+The FILES signature:
+
+::
+
+  install(FILES files... DESTINATION <dir>
+          [PERMISSIONS permissions...]
+          [CONFIGURATIONS [Debug|Release|...]]
+          [COMPONENT <component>]
+          [RENAME <name>] [OPTIONAL])
+
+The FILES form specifies rules for installing files for a project.
+File names given as relative paths are interpreted with respect to the
+current source directory.  Files installed by this form are by default
+given permissions OWNER_WRITE, OWNER_READ, GROUP_READ, and WORLD_READ
+if no PERMISSIONS argument is given.
+
+The PROGRAMS signature:
+
+::
+
+  install(PROGRAMS files... DESTINATION <dir>
+          [PERMISSIONS permissions...]
+          [CONFIGURATIONS [Debug|Release|...]]
+          [COMPONENT <component>]
+          [RENAME <name>] [OPTIONAL])
+
+The PROGRAMS form is identical to the FILES form except that the
+default permissions for the installed file also include OWNER_EXECUTE,
+GROUP_EXECUTE, and WORLD_EXECUTE.  This form is intended to install
+programs that are not targets, such as shell scripts.  Use the TARGETS
+form to install targets built within the project.
+
+The DIRECTORY signature:
+
+::
+
+  install(DIRECTORY dirs... DESTINATION <dir>
+          [FILE_PERMISSIONS permissions...]
+          [DIRECTORY_PERMISSIONS permissions...]
+          [USE_SOURCE_PERMISSIONS] [OPTIONAL]
+          [CONFIGURATIONS [Debug|Release|...]]
+          [COMPONENT <component>] [FILES_MATCHING]
+          [[PATTERN <pattern> | REGEX <regex>]
+           [EXCLUDE] [PERMISSIONS permissions...]] [...])
+
+The DIRECTORY form installs contents of one or more directories to a
+given destination.  The directory structure is copied verbatim to the
+destination.  The last component of each directory name is appended to
+the destination directory but a trailing slash may be used to avoid
+this because it leaves the last component empty.  Directory names
+given as relative paths are interpreted with respect to the current
+source directory.  If no input directory names are given the
+destination directory will be created but nothing will be installed
+into it.  The FILE_PERMISSIONS and DIRECTORY_PERMISSIONS options
+specify permissions given to files and directories in the destination.
+If USE_SOURCE_PERMISSIONS is specified and FILE_PERMISSIONS is not,
+file permissions will be copied from the source directory structure.
+If no permissions are specified files will be given the default
+permissions specified in the FILES form of the command, and the
+directories will be given the default permissions specified in the
+PROGRAMS form of the command.
+
+Installation of directories may be controlled with fine granularity
+using the PATTERN or REGEX options.  These "match" options specify a
+globbing pattern or regular expression to match directories or files
+encountered within input directories.  They may be used to apply
+certain options (see below) to a subset of the files and directories
+encountered.  The full path to each input file or directory (with
+forward slashes) is matched against the expression.  A PATTERN will
+match only complete file names: the portion of the full path matching
+the pattern must occur at the end of the file name and be preceded by
+a slash.  A REGEX will match any portion of the full path but it may
+use '/' and '$' to simulate the PATTERN behavior.  By default all
+files and directories are installed whether or not they are matched.
+The FILES_MATCHING option may be given before the first match option
+to disable installation of files (but not directories) not matched by
+any expression.  For example, the code
+
+::
+
+  install(DIRECTORY src/ DESTINATION include/myproj
+          FILES_MATCHING PATTERN "*.h")
+
+will extract and install header files from a source tree.
+
+Some options may follow a PATTERN or REGEX expression and are applied
+only to files or directories matching them.  The EXCLUDE option will
+skip the matched file or directory.  The PERMISSIONS option overrides
+the permissions setting for the matched file or directory.  For
+example the code
+
+::
+
+  install(DIRECTORY icons scripts/ DESTINATION share/myproj
+          PATTERN "CVS" EXCLUDE
+          PATTERN "scripts/*"
+          PERMISSIONS OWNER_EXECUTE OWNER_WRITE OWNER_READ
+                      GROUP_EXECUTE GROUP_READ)
+
+will install the icons directory to share/myproj/icons and the scripts
+directory to share/myproj.  The icons will get default file
+permissions, the scripts will be given specific permissions, and any
+CVS directories will be excluded.
+
+The SCRIPT and CODE signature:
+
+::
+
+  install([[SCRIPT <file>] [CODE <code>]] [...])
+
+The SCRIPT form will invoke the given CMake script files during
+installation.  If the script file name is a relative path it will be
+interpreted with respect to the current source directory.  The CODE
+form will invoke the given CMake code during installation.  Code is
+specified as a single argument inside a double-quoted string.  For
+example, the code
+
+::
+
+  install(CODE "MESSAGE(\"Sample install message.\")")
+
+will print a message during installation.
+
+The EXPORT signature:
+
+::
+
+  install(EXPORT <export-name> DESTINATION <dir>
+          [NAMESPACE <namespace>] [FILE <name>.cmake]
+          [PERMISSIONS permissions...]
+          [CONFIGURATIONS [Debug|Release|...]]
+          [EXPORT_LINK_INTERFACE_LIBRARIES]
+          [COMPONENT <component>])
+
+The EXPORT form generates and installs a CMake file containing code to
+import targets from the installation tree into another project.
+Target installations are associated with the export <export-name>
+using the EXPORT option of the install(TARGETS ...) signature
+documented above.  The NAMESPACE option will prepend <namespace> to
+the target names as they are written to the import file.  By default
+the generated file will be called <export-name>.cmake but the FILE
+option may be used to specify a different name.  The value given to
+the FILE option must be a file name with the ".cmake" extension.  If a
+CONFIGURATIONS option is given then the file will only be installed
+when one of the named configurations is installed.  Additionally, the
+generated import file will reference only the matching target
+configurations.  The EXPORT_LINK_INTERFACE_LIBRARIES keyword, if
+present, causes the contents of the properties matching
+``(IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?`` to be exported, when
+policy CMP0022 is NEW.  If a COMPONENT option is specified that does
+not match that given to the targets associated with <export-name> the
+behavior is undefined.  If a library target is included in the export
+but a target to which it links is not included the behavior is
+unspecified.
+
+The EXPORT form is useful to help outside projects use targets built
+and installed by the current project.  For example, the code
+
+::
+
+  install(TARGETS myexe EXPORT myproj DESTINATION bin)
+  install(EXPORT myproj NAMESPACE mp_ DESTINATION lib/myproj)
+
+will install the executable myexe to <prefix>/bin and code to import
+it in the file "<prefix>/lib/myproj/myproj.cmake".  An outside project
+may load this file with the include command and reference the myexe
+executable from the installation tree using the imported target name
+mp_myexe as if the target were built in its own tree.
+
+NOTE: This command supercedes the INSTALL_TARGETS command and the
+target properties PRE_INSTALL_SCRIPT and POST_INSTALL_SCRIPT.  It also
+replaces the FILES forms of the INSTALL_FILES and INSTALL_PROGRAMS
+commands.  The processing order of these install rules relative to
+those generated by INSTALL_TARGETS, INSTALL_FILES, and
+INSTALL_PROGRAMS commands is not defined.

+The list subcommands APPEND, INSERT, REMOVE_AT, REMOVE_ITEM,

+propagate the results of these operations upwards, use SET with
+PARENT_SCOPE, SET with CACHE INTERNAL, or some other means of value
+propagation.
+
+NOTES: A list in cmake is a ; separated group of strings.  To create a
+list the set command can be used.  For example, set(var a b c d e)
+creates a list with a;b;c;d;e, and set(var "a b c d e") creates a
+string or a list with one item in it.
+
+When specifying index values, if <element index> is 0 or greater, it
+is indexed from the beginning of the list, with 0 representing the
+first list element.  If <element index> is -1 or lesser, it is indexed
+from the end of the list, with -1 representing the last list element.
+Be careful when counting with negative indices: they do not start from
+0.  -0 is equivalent to 0, the first list element.
