- ``MODULES <module_files>...``
|

|
|
|
- that are typically created with :command:`add_library(MODULE)`, but they
|
|
|
- do not have to be created by CMake. They are typically used by calling

|
|
- List of additional directories to search for dependencies. On Linux
|
|

|
|
- in any of the other usual paths. If it is found in such a directory, a

|
- On Windows platforms, these directories are searched if the dependency

- ``BUNDLE_EXECUTABLE <bundle_executable_file>``
|
|
|
- Executable to treat as the "bundle executable" when resolving libraries.

|
- On Apple platforms, this argument determines the value of

+ ``OUTPUT <output-file>``
|
|
|
+ Specify the output file name to generate. Use generator expressions

|
+ such as :genex:`$<CONFIG>` to specify a configuration-specific
|
|
|
+ output file name. Multiple configurations may generate the same output
|

|
|
|
- List of post-include regexes through which to filter the names of

|
|
- resolved dependencies.
|
|
|
+ Specify which target to use when evaluating generator expressions that

|
|
+ require a target for evaluation (e.g.

+ :genex:`$<COMPILE_FEATURES:...>`,
|
|
|
+ :genex:`$<TARGET_PROPERTY:prop>`).
|

|
|
|
|
|
|
- ``POST_EXCLUDE_FILES <files>...``
|
|
|
- .. versionadded:: 3.21
|
|
|
+ Transfer the file permissions of the ``INPUT`` file to the generated
|
|
|
+ file. This is already the default behavior if none of the three
|
|
|
+ permissions-related keywords are given (``NO_SOURCE_PERMISSIONS``,
|
|
|
+ ``USE_SOURCE_PERMISSIONS`` or ``FILE_PERMISSIONS``). The
|
|
|
+ ``USE_SOURCE_PERMISSIONS`` keyword mostly serves as a way of making
|
|
|
+ the intended behavior clearer at the call site. It is an error to
|
|
|
+ specify this option without ``INPUT``.

|
|
|
- List of post-exclude filenames through which to filter the names of

+ ``FILE_PERMISSIONS <permissions>...``
|

+ .. versionadded:: 3.20
|
|
|
|
|
|
- These arguments can be used to exclude unwanted system libraries when
|
|
|
- resolving the dependencies, or to include libraries from a specific
|
|
|
- directory. The filtering works as follows:
|
|
|
+ Use the specified permissions for the generated file.
|
|
|
|
|
|
- 1. If the not-yet-resolved dependency matches any of the
|
|
|
- ``PRE_INCLUDE_REGEXES``, steps 2 and 3 are skipped, and the dependency
|
|
|
- resolution proceeds to step 4.
|
|
|
+ ``NEWLINE_STYLE <style>``
|
|
|
+ .. versionadded:: 3.20
|
|
|
|
|
|
- 2. If the not-yet-resolved dependency matches any of the
|
|
|
- ``PRE_EXCLUDE_REGEXES``, dependency resolution stops for that dependency.
|
|
|
+ Specify the newline style for the generated file. Specify
|
|
|
+ ``UNIX`` or ``LF`` for ``\n`` newlines, or specify
|
|
|
+ ``DOS``, ``WIN32``, or ``CRLF`` for ``\r\n`` newlines.
|
|
|
|
|
|
- 3. Otherwise, dependency resolution proceeds.
|
|
|
+ Exactly one ``CONTENT`` or ``INPUT`` option must be given. A specific
|
|
|
+ ``OUTPUT`` file may be named by at most one invocation of ``file(GENERATE)``.
|
|
|
+ Generated files are modified and their timestamp updated on subsequent cmake
|
|
|
+ runs only if their content is changed.
|
|
|
|
|
|
- 4. ``file(GET_RUNTIME_DEPENDENCIES)`` searches for the dependency according
|
|
|
- to the linking rules of the platform (see below).
|
|
|
+ Note also that ``file(GENERATE)`` does not create the output file until the
|
|
|
+ generation phase. The output file will not yet have been written when the
|
|
|
+ ``file(GENERATE)`` command returns, it is written only after processing all
|
|
|
+ of a project's ``CMakeLists.txt`` files.
|
|
|
|
|
|
- 5. If the dependency is found, and its full path matches one of the
|
|
|
- ``POST_INCLUDE_REGEXES`` or ``POST_INCLUDE_FILES``, the full path is added
|
|
|
- to the resolved dependencies, and ``file(GET_RUNTIME_DEPENDENCIES)``
|
|
|
- recursively resolves that library's own dependencies. Otherwise, resolution
|
|
|
- proceeds to step 6.

|
|
|
- ``POST_EXCLUDE_REGEXES`` or ``POST_EXCLUDE_FILES``, it is not added to the

|
- resolved dependencies, and dependency resolution stops for that dependency.
|

|
|
|
- ``POST_INCLUDE_REGEXES``, ``POST_INCLUDE_FILES``, ``POST_EXCLUDE_REGEXES``,
|
|
|
- or ``POST_EXCLUDE_FILES``, the full path is added to the resolved
|
|
|
- dependencies, and ``file(GET_RUNTIME_DEPENDENCIES)`` recursively resolves
|
|
|
- that library's own dependencies.
|
|
|
+ Generate an output file using the input given by ``CONTENT`` and substitute
|
|
|
+ variable values referenced as ``@VAR@`` or ``${VAR}`` contained therein. The
|
|
|
+ substitution rules behave the same as the :command:`configure_file` command.
|
|
|
+ In order to match :command:`configure_file`'s behavior, generator expressions
|
|
|
+ are not supported for both ``OUTPUT`` and ``CONTENT``.
|
|
|
|
|
|
- Different platforms have different rules for how dependencies are resolved.
|
|
|
- These specifics are described here.
|
|
|
+ The arguments are:
|
|
|
|
|
|
- On Linux platforms, library resolution works as follows:
|
|
|
+ ``OUTPUT <output-file>``
|
|
|
+ Specify the output file name to generate. A relative path is treated with
|
|
|
+ respect to the value of :variable:`CMAKE_CURRENT_BINARY_DIR`.
|
|
|
+ ``<output-file>`` does not support generator expressions.
|
|
|
|
|
|
- 1. If the depending file does not have any ``RUNPATH`` entries, and the
|
|
|
- library exists in one of the depending file's ``RPATH`` entries, or its
|
|
|
- parents', in that order, the dependency is resolved to that file.
|
|
|
- 2. Otherwise, if the depending file has any ``RUNPATH`` entries, and the
|
|
|
- library exists in one of those entries, the dependency is resolved to that
|
|
|
- file.
|
|
|
- 3. Otherwise, if the library exists in one of the directories listed by
|
|
|
- ``ldconfig``, the dependency is resolved to that file.
|
|
|
- 4. Otherwise, if the library exists in one of the ``DIRECTORIES`` entries,
|
|
|
- the dependency is resolved to that file. In this case, a warning is
|
|
|
- issued, because finding a file in one of the ``DIRECTORIES`` means that
|
|
|
- the depending file is not complete (it does not list all the directories
|
|
|
- from which it pulls dependencies).
|
|
|
-
|
|
|
- 5. Otherwise, the dependency is unresolved.
|
|
|
-
|
|
|
- On Windows platforms, library resolution works as follows:
|
|
|
+ ``CONTENT <content>``
|
|
|
+ Use the content given explicitly as input.
|
|
|
+ ``<content>`` does not support generator expressions.
|
|
|
|
|
|
- 1. DLL dependency names are converted to lowercase for matching filters.
|
|
|
- Windows DLL names are case-insensitive, and some linkers mangle the
|
|
|
- case of the DLL dependency names. However, this makes it more difficult
|
|
|
- for ``PRE_INCLUDE_REGEXES``, ``PRE_EXCLUDE_REGEXES``,
|
|
|
- ``POST_INCLUDE_REGEXES``, and ``POST_EXCLUDE_REGEXES`` to properly
|
|
|
- filter DLL names - every regex would have to check for both uppercase
|
|
|
- and lowercase letters. For example:
|
|
|
+ ``ESCAPE_QUOTES``
|
|
|
+ Escape any substituted quotes with backslashes (C-style).
|
|
|
|
|
|
- .. code-block:: cmake
|
|
|
+ ``@ONLY``
|
|
|
+ Restrict variable replacement to references of the form ``@VAR@``.
|
|
|
+ This is useful for configuring scripts that use ``${VAR}`` syntax.
|
|
|
|
|
|

- PRE_INCLUDE_REGEXES "^[Mm][Yy][Ll][Ii][Bb][Rr][Aa][Rr][Yy]\\.[Dd][Ll][Ll]$"

|
|
|
+ ``NEWLINE_STYLE <style>``
|
|

|
|
+ ``DOS``, ``WIN32``, or ``CRLF`` for ``\r\n`` newlines.
|
|
|
|
|
|
- Converting the DLL name to lowercase allows the regexes to only match
|
|
|
- lowercase names, thus simplifying the regex. For example:

|
+ On Windows and macOS, globbing is case-insensitive even if the underlying
|
|
|
+ filesystem is case-sensitive (both filenames and globbing expressions are
|
|
|
+ converted to lowercase before matching). On other platforms, globbing is
|
|
|
+ case-sensitive.
|
|
|
|
|
|
- The conversion to lowercase only applies while matching filters.
|
|
|
- Results reported after filtering case-preserve each DLL name as it is
|
|
|
- found on disk, if resolved, and otherwise as it is referenced by the
|
|
|
- dependent binary.
|
|
|
+ .. versionadded:: 3.3
|
|
|
+ By default ``GLOB`` lists directories. Directories are omitted in the
|
|
|
+ result if ``LIST_DIRECTORIES`` is set to false.
|
|
|
|
|
|
- Prior to CMake 3.27, the results were reported with lowercase DLL
|
|
|
- file names, but the directory portion retained its casing.
|
|
|
+ .. versionadded:: 3.12
|
|
|
+ If the ``CONFIGURE_DEPENDS`` flag is specified, CMake will add logic
|
|
|
+ to the main build system check target to rerun the flagged ``GLOB``
|
|
|
+ commands at build time. If any of the outputs change, CMake will regenerate
|
|
|
+ the build system.

|
- 2. (**Not yet implemented**) If the depending file is a Windows Store app,
|
|
|
- and the dependency is listed as a dependency in the application's package
|
|
|
- manifest, the dependency is resolved to that file.
|
|
|
+ .. note::
|
|
|
+ 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.
|
|
|
+ The ``CONFIGURE_DEPENDS`` flag may not work reliably on all generators, or
|
|
|
+ if a new generator is added in the future that cannot support it, projects
|
|
|
+ using it will be stuck. Even if ``CONFIGURE_DEPENDS`` works reliably, there
|
|
|

|
|
|
- other directories is a normal part of Windows library resolution.
|
|
|
+ The ``GLOB_RECURSE`` mode will traverse all the subdirectories of the
|
|
|
+ matched directory and match the files. Subdirectories that are symlinks
|
|
|

|
|
|
|
|
|
- 6. Otherwise, the dependency is unresolved.
|
|

|
|
|
+ By default ``GLOB_RECURSE`` omits directories from result list. Setting

|
|
|
+ If ``FOLLOW_SYMLINKS`` is given or policy :policy:`CMP0009` is not set to

|
|
- We do not recommend using GLOB to collect a list of source files from

- The ``CONFIGURE_DEPENDS`` flag may not work reliably on all generators, or

|
- if a new generator is added in the future that cannot support it, projects

|
|
|
- If ``FOLLOW_SYMLINKS`` is given or policy :policy:`CMP0009` is not set to

|
|
+ If the ``<path>`` is ``~`` or starts with ``~/``, the ``~`` is replaced
|
|
|
+ by the user's home directory. The path to the home directory is obtained

+ from environment variables. On Windows, the ``USERPROFILE`` environment
|
|
|
+ variable is used, falling back to the ``HOME`` environment variable
|
|

|
- For each symlink that is installed, the resolution is stripped of the
|
|
|
- directory, leaving only the filename, meaning that the new symlink points
|
|
|
- to a file in the same directory as the symlink. This feature is useful on
|
|
|
- some Unix systems, where libraries are installed as a chain of symlinks
|
|
|
- with version numbers, with less specific versions pointing to more specific
|
|
|
- versions. ``FOLLOW_SYMLINK_CHAIN`` will install all of these symlinks and
|
|
|
- the library itself into the destination directory. For example, if you have
|
|
|
- the following directory structure:
|
|
|
+ ``REQUIRED``
|
|
|
+ The .netrc file is required, and information in the URL is ignored.

|
|
|
|
|
|
- Create a link ``<linkname>`` that points to ``<original>``.
|
|
|
- It will be a hard link by default, but providing the ``SYMBOLIC`` option
|
|
|
- results in a symbolic link instead. Hard links require that ``original``
|
|
|
- exists and is a file, not a directory. If ``<linkname>`` already exists,
|
|
|
- it will be overwritten.
|
|
|
+ Lock a file specified by ``<path>`` if no ``DIRECTORY`` option present and
|
|
|
+ file ``<path>/cmake.lock`` otherwise. The file will be locked for the scope
|
|
|
+ defined by the ``GUARD`` option (default value is ``PROCESS``). The
|
|
|
+ ``RELEASE`` option can be used to unlock the file explicitly. If the
|
|
|
+ ``TIMEOUT`` option is not specified, CMake will wait until the lock succeeds
|
|
|
+ or until a fatal error occurs. If ``TIMEOUT`` is set to ``0``, locking will
|
|
|
+ be tried once and the result will be reported immediately. If ``TIMEOUT``
|
|
|
+ is not ``0``, CMake will try to lock the file for the period specified by
|
|
|
+ the ``TIMEOUT <seconds>`` value. Any errors will be interpreted as fatal if
|
|
|
+ there is no ``RESULT_VARIABLE`` option. Otherwise, the result will be stored
|
|
|
+ in ``<variable>`` and will be ``0`` on success or an error message on
|
|
|
+ failure.
|
|
|
|
|
|
- The ``<result>`` variable, if specified, receives the status of the
|
|
|
- operation. It is set to ``0`` upon success or an error message otherwise.
|
|
|
- If ``RESULT`` is not specified and the operation fails, a fatal error is
|
|
|
- emitted.
|
|
|
+ Note that lock is advisory; there is no guarantee that other processes will
|
|
|
+ respect this lock, i.e. lock synchronize two or more CMake instances sharing
|
|
|
+ some modifiable resources. Similar logic applies to the ``DIRECTORY`` option;
|
|
|
+ locking a parent directory doesn't prevent other ``LOCK`` commands from
|
|
|
+ locking any child directory or file.
|
|
|
|
|
|
- Specifying ``COPY_ON_ERROR`` enables copying the file as a fallback if
|
|
|
- creating the link fails. It can be useful for handling situations such as
|
|
|
- ``<original>`` and ``<linkname>`` being on different drives or mount points,
|
|
|
- which would make them unable to support a hard link.
|
|
|
+ Trying to lock the same file twice is not allowed. Any intermediate
|
|
|
+ directories and the file itself will be created if they not exist. The
|
|
|
+ ``GUARD`` and ``TIMEOUT`` options are ignored on the ``RELEASE`` operation.

|
|
- The ``DOWNLOAD`` subcommand downloads the given ``<url>`` to a local
|
|
|
- ``<file>``. The ``UPLOAD`` mode uploads a local ``<file>`` to a given
|
|
|
- ``<url>``.
|
|
|
+ ``CONFLICTING_DEPENDENCIES_PREFIX <conflicting_deps_prefix>``
|
|
|
+ Variable prefix in which to store conflicting dependency information.
|
|
|
+ Dependencies are conflicting if two files with the same name are found in
|
|
|
+ two different directories. The list of filenames that conflict are stored
|
|
|
+ in ``<conflicting_deps_prefix>_FILENAMES``. For each filename, the list
|
|
|
+ of paths that were found for that filename are stored in
|
|
|
+ ``<conflicting_deps_prefix>_<filename>``.
|
|
|
|
|
|
- .. versionadded:: 3.19
|
|
|
- If ``<file>`` is not specified for ``file(DOWNLOAD)``, the file is not
|
|
|
- saved. This can be useful if you want to know if a file can be downloaded
|
|
|
- (for example, to check that it exists) without actually saving it anywhere.
|
|
|
+ ``EXECUTABLES <executable_files>...``
|
|
|
+ List of executable files to read for dependencies. These are executables
|
|
|
+ that are typically created with :command:`add_executable`, but they do
|
|
|
+ not have to be created by CMake. On Apple platforms, the paths to these
|
|
|
+ files determine the value of ``@executable_path`` when recursively
|
|
|
+ resolving the libraries. Specifying any kind of library (``STATIC``,
|
|
|
+ ``MODULE``, or ``SHARED``) here will result in undefined behavior.
|
|
|
|
|
|
- Options to both ``DOWNLOAD`` and ``UPLOAD`` are:
|
|
|
+ ``LIBRARIES <library_files>...``
|
|
|
+ List of library files to read for dependencies. These are libraries that
|
|
|
+ are typically created with :command:`add_library(SHARED)`, but they do
|
|
|
+ not have to be created by CMake. Specifying ``STATIC`` libraries,
|
|
|
+ ``MODULE`` libraries, or executables here will result in undefined
|
|
|
+ behavior.
|
|
|
|
|
|
- ``INACTIVITY_TIMEOUT <seconds>``
|
|
|
- Terminate the operation after a period of inactivity.
|
|
|
+ ``MODULES <module_files>...``
|
|
|
+ List of loadable module files to read for dependencies. These are modules
|
|
|
+ that are typically created with :command:`add_library(MODULE)`, but they
|
|
|
+ do not have to be created by CMake. They are typically used by calling
|
|
|
+ ``dlopen()`` at runtime rather than linked at link time with ``ld -l``.
|
|
|
+ Specifying ``STATIC`` libraries, ``SHARED`` libraries, or executables
|
|
|
+ here will result in undefined behavior.
|
|
|
|
|
|
- ``LOG <variable>``
|
|
|
- Store a human-readable log of the operation in a variable.
|
|
|
+ ``DIRECTORIES <directories>...``
|
|
|
+ List of additional directories to search for dependencies. On Linux
|
|
|
+ platforms, these directories are searched if the dependency is not found
|
|
|
+ in any of the other usual paths. If it is found in such a directory, a
|
|
|
+ warning is issued, because it means that the file is incomplete (it does
|
|
|
+ not list all of the directories that contain its dependencies).
|
|
|
+ On Windows platforms, these directories are searched if the dependency
|
|
|
+ is not found in any of the other search paths, but no warning is issued,
|
|
|
+ because searching other paths is a normal part of Windows dependency
|
|
|
+ resolution. On Apple platforms, this argument has no effect.
|
|
|
|
|
|
- ``SHOW_PROGRESS``
|
|
|
- Print progress information as status messages until the operation is
|
|
|
- complete.
|
|
|
+ ``BUNDLE_EXECUTABLE <bundle_executable_file>``
|
|
|
+ Executable to treat as the "bundle executable" when resolving libraries.
|
|
|
+ On Apple platforms, this argument determines the value of
|
|
|
+ ``@executable_path`` when recursively resolving libraries for
|
|
|
+ ``LIBRARIES`` and ``MODULES`` files. It has no effect on ``EXECUTABLES``
|
|
|
+ files. On other platforms, it has no effect. This is typically (but not
|
|
|
+ always) one of the executables in the ``EXECUTABLES`` argument which
|
|
|
+ designates the "main" executable of the package.
|
|
|
|
|
|
- ``STATUS <variable>``
|
|
|
- Store the resulting status of the operation in a variable.
|
|
|
- The status is a ``;`` separated 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.
|
|
|
+ The following arguments specify filters for including or excluding libraries
|
|
|
+ to be resolved. See below for a full description of how they work.
|
|
|
|
|
|
- ``TIMEOUT <seconds>``
|
|
|
- Terminate the operation after a given total time has elapsed.
|
|
|
+ ``PRE_INCLUDE_REGEXES <regexes>...``
|
|
|
+ List of pre-include regexes through which to filter the names of
|
|
|
+ not-yet-resolved dependencies.
|
|
|
|
|
|
- ``USERPWD <username>:<password>``
|
|
|
- .. versionadded:: 3.7
|
|
|
+ ``PRE_EXCLUDE_REGEXES <regexes>...``
|
|
|
+ List of pre-exclude regexes through which to filter the names of
|
|
|
+ not-yet-resolved dependencies.
|
|
|
|
|
|
- Set username and password for operation.
|
|
|
+ ``POST_INCLUDE_REGEXES <regexes>...``
|
|
|
+ List of post-include regexes through which to filter the names of
|
|
|
+ resolved dependencies.
|
|
|
|
|
|
- ``HTTPHEADER <HTTP-header>``
|
|
|
- .. versionadded:: 3.7
|
|
|
+ ``POST_EXCLUDE_REGEXES <regexes>...``
|
|
|
+ List of post-exclude regexes through which to filter the names of
|
|
|
+ resolved dependencies.
|
|
|
|
|
|
- HTTP header for ``DOWNLOAD`` and ``UPLOAD`` operations. ``HTTPHEADER``
|
|
|
- can be repeated for multiple options:
|
|
|
+ ``POST_INCLUDE_FILES <files>...``
|
|
|
+ .. versionadded:: 3.21
|
|
|
|
|
|
- .. code-block:: cmake
|
|
|
+ List of post-include filenames through which to filter the names of
|
|
|
+ resolved dependencies. Symlinks are resolved when attempting to match
|
|
|
+ these filenames.
|
|
|
|
|
|
- file(DOWNLOAD <url>
|
|
|
- HTTPHEADER "Authorization: Bearer <auth-token>"
|
|
|
- HTTPHEADER "UserAgent: Mozilla/5.0")
|
|
|
+ ``POST_EXCLUDE_FILES <files>...``
|
|
|
+ .. versionadded:: 3.21
|
|
|
|
|
|
- ``NETRC <level>``
|
|
|
- .. versionadded:: 3.11
|
|
|
+ List of post-exclude filenames through which to filter the names of
|
|
|
+ resolved dependencies. Symlinks are resolved when attempting to match
|
|
|
+ these filenames.
|
|
|
|
|
|
- Specify whether the .netrc file is to be used for operation. If this
|
|
|
- option is not specified, the value of the :variable:`CMAKE_NETRC`
|
|
|
- variable will be used instead.
|
|
|
+ These arguments can be used to exclude unwanted system libraries when
|
|
|
+ resolving the dependencies, or to include libraries from a specific
|
|
|
+ directory. The filtering works as follows:
|
|
|
|
|
|
- Valid levels are:
|
|
|
+ 1. If the not-yet-resolved dependency matches any of the
|
|
|
+ ``PRE_INCLUDE_REGEXES``, steps 2 and 3 are skipped, and the dependency
|
|
|
+ resolution proceeds to step 4.
|
|
|
|
|
|
- ``IGNORED``
|
|
|
- The .netrc file is ignored.
|
|
|
- This is the default.
|
|
|
+ 2. If the not-yet-resolved dependency matches any of the
|
|
|
+ ``PRE_EXCLUDE_REGEXES``, dependency resolution stops for that dependency.
|
|
|
|
|
|
- ``OPTIONAL``
|
|
|
- The .netrc file is optional, and information in the URL is preferred.
|
|
|
- The file will be scanned to find which ever information is not
|
|
|
- specified in the URL.
|
|
|
+ 3. Otherwise, dependency resolution proceeds.
|
|
|
|
|
|
- ``REQUIRED``
|
|
|
- The .netrc file is required, and information in the URL is ignored.
|
|
|
+ 4. ``file(GET_RUNTIME_DEPENDENCIES)`` searches for the dependency according
|
|
|
+ to the linking rules of the platform (see below).
|
|
|
|
|
|
- ``NETRC_FILE <file>``
|
|
|
- .. versionadded:: 3.11
|
|
|
+ 5. If the dependency is found, and its full path matches one of the
|
|
|
+ ``POST_INCLUDE_REGEXES`` or ``POST_INCLUDE_FILES``, the full path is added
|
|
|
+ to the resolved dependencies, and ``file(GET_RUNTIME_DEPENDENCIES)``
|
|
|
+ recursively resolves that library's own dependencies. Otherwise, resolution
|
|
|
+ proceeds to step 6.
|
|
|
|
|
|
- Specify an alternative .netrc file to the one in your home directory,
|
|
|
- if the ``NETRC`` level is ``OPTIONAL`` or ``REQUIRED``. If this option
|
|
|
- is not specified, the value of the :variable:`CMAKE_NETRC_FILE` variable
|
|
|
- will be used instead.
|
|
|
+ 6. If the dependency is found, but its full path matches one of the
|
|
|
+ ``POST_EXCLUDE_REGEXES`` or ``POST_EXCLUDE_FILES``, it is not added to the
|
|
|
+ resolved dependencies, and dependency resolution stops for that dependency.
|
|
|
|
|
|
- ``TLS_VERSION <min>``
|
|
|
- .. versionadded:: 3.30
|
|
|
+ 7. If the dependency is found, and its full path does not match either
|
|
|
+ ``POST_INCLUDE_REGEXES``, ``POST_INCLUDE_FILES``, ``POST_EXCLUDE_REGEXES``,
|
|
|
+ or ``POST_EXCLUDE_FILES``, the full path is added to the resolved
|
|
|
+ dependencies, and ``file(GET_RUNTIME_DEPENDENCIES)`` recursively resolves
|
|
|
+ that library's own dependencies.
|
|
|
|
|
|
- Specify minimum TLS version for ``https://`` URLs.
|
|
|
- If this option is not specified, the value of the
|
|
|
- :variable:`CMAKE_TLS_VERSION` variable or :envvar:`CMAKE_TLS_VERSION`
|
|
|
- environment variable will be used instead.
|
|
|
- See :variable:`CMAKE_TLS_VERSION` for allowed values.
|
|
|
+ Different platforms have different rules for how dependencies are resolved.
|
|
|
+ These specifics are described here.
|
|
|
|
|
|
- ``TLS_VERIFY <ON|OFF>``
|
|
|
- Specify whether to verify the server certificate for ``https://`` URLs.
|
|
|
- The default is to *not* verify. If this option is not specified, the
|
|
|
- value of the :variable:`CMAKE_TLS_VERIFY` variable will be used instead.
|
|
|
+ On Linux platforms, library resolution works as follows:
|
|
|
|
|
|
- .. versionadded:: 3.18
|
|
|
- Added support to ``file(UPLOAD)``.
|
|
|
+ 1. If the depending file does not have any ``RUNPATH`` entries, and the
|
|
|
+ library exists in one of the depending file's ``RPATH`` entries, or its
|
|
|
+ parents', in that order, the dependency is resolved to that file.
|
|
|
+ 2. Otherwise, if the depending file has any ``RUNPATH`` entries, and the
|
|
|
+ library exists in one of those entries, the dependency is resolved to that
|
|
|
+ file.
|
|
|
+ 3. Otherwise, if the library exists in one of the directories listed by
|
|
|
+ ``ldconfig``, the dependency is resolved to that file.
|
|
|
+ 4. Otherwise, if the library exists in one of the ``DIRECTORIES`` entries,
|
|
|
+ the dependency is resolved to that file. In this case, a warning is
|
|
|
+ issued, because finding a file in one of the ``DIRECTORIES`` means that
|
|
|
+ the depending file is not complete (it does not list all the directories
|
|
|
+ from which it pulls dependencies).
|
|
|
|
|
|
- ``TLS_CAINFO <file>``
|
|
|
- Specify a custom Certificate Authority file for ``https://`` URLs.
|
|
|
- If this option is not specified, the value of the
|
|
|
- :variable:`CMAKE_TLS_CAINFO` variable will be used instead.
|
|
|
+ 5. Otherwise, the dependency is unresolved.
|
|
|
|
|
|
- .. versionadded:: 3.18
|
|
|
- Added support to ``file(UPLOAD)``.
|
|
|
+ On Windows platforms, library resolution works as follows:
|
|
|
|
|
|
- For ``https://`` URLs CMake must be built with OpenSSL support. ``TLS/SSL``
|
|
|
- certificates are not checked by default. Set ``TLS_VERIFY`` to ``ON`` to
|
|
|
- check certificates.
|
|
|
+ 1. DLL dependency names are converted to lowercase for matching filters.
|
|
|
+ Windows DLL names are case-insensitive, and some linkers mangle the
|
|
|
+ case of the DLL dependency names. However, this makes it more difficult
|
|
|
+ for ``PRE_INCLUDE_REGEXES``, ``PRE_EXCLUDE_REGEXES``,
|
|
|
+ ``POST_INCLUDE_REGEXES``, and ``POST_EXCLUDE_REGEXES`` to properly
|
|
|
+ filter DLL names - every regex would have to check for both uppercase
|
|
|
+ and lowercase letters. For example:
|
|
|
|
|
|
- Additional options to ``DOWNLOAD`` are:
|
|
|
+ .. code-block:: cmake
|
|
|
|
|
|
- ``EXPECTED_HASH <algorithm>=<value>``
|
|
|
- Verify that the downloaded content hash matches the expected value, where
|
|
|
- ``<algorithm>`` is one of the algorithms supported by :cref:`<HASH>`.
|
|
|
- If the file already exists and matches the hash, the download is skipped.
|
|
|
- If the file already exists and does not match the hash, the file is
|
|
|
- downloaded again. If after download the file does not match the hash, the
|
|
|
- operation fails with an error. It is an error to specify this option if
|
|
|
- ``DOWNLOAD`` is not given a ``<file>``.
|
|
|
+ file(GET_RUNTIME_DEPENDENCIES
|
|
|
+ # ...
|
|
|
+ PRE_INCLUDE_REGEXES "^[Mm][Yy][Ll][Ii][Bb][Rr][Aa][Rr][Yy]\\.[Dd][Ll][Ll]$"
|
|
|
+ )
|
|
|
|
|
|
- ``EXPECTED_MD5 <value>``
|
|
|
- Historical short-hand for ``EXPECTED_HASH MD5=<value>``. It is an error
|
|
|
- to specify this if ``DOWNLOAD`` is not given a ``<file>``.
|
|
|
+ Converting the DLL name to lowercase allows the regexes to only match
|
|
|
+ lowercase names, thus simplifying the regex. For example:
|
|
|
|
|
|
- ``RANGE_START <value>``
|
|
|
- .. versionadded:: 3.24
|
|
|
+ .. code-block:: cmake
|
|
|
|
|
|
- Offset of the start of the range in file in bytes. Could be omitted to
|
|
|
- download up to the specified ``RANGE_END``.
|
|
|
+ file(GET_RUNTIME_DEPENDENCIES
|
|
|
+ # ...
|
|
|
+ PRE_INCLUDE_REGEXES "^mylibrary\\.dll$"
|
|
|
+ )
|
|
|
|
|
|
- ``RANGE_END <value>``
|
|
|
- .. versionadded:: 3.24
|
|
|
+ This regex will match ``mylibrary.dll`` regardless of how it is cased,
|
|
|
+ either on disk or in the depending file. (For example, it will match
|
|
|
+ ``mylibrary.dll``, ``MyLibrary.dll``, and ``MYLIBRARY.DLL``.)
|
|
|
|
|
|
- Offset of the end of the range in file in bytes. Could be omitted to
|
|
|
- download everything from the specified ``RANGE_START`` to the end of
|
|
|
- file.

|
|

-Locking
|
|
|
-^^^^^^^
|
|
|
+ The conversion to lowercase only applies while matching filters.
|
|
|
+ Results reported after filtering case-preserve each DLL name as it is
|
|
|
+ found on disk, if resolved, and otherwise as it is referenced by the
|
|
|
+ dependent binary.

|
- [GUARD <FUNCTION|FILE|PROCESS>]
|
|
|
- [RESULT_VARIABLE <variable>]
|
|
|
- [TIMEOUT <seconds>])
|
|
|
+ Prior to CMake 3.27, the results were reported with lowercase DLL
|
|
|
+ file names, but the directory portion retained its casing.
|
|
|
|
|
|
- .. versionadded:: 3.2
|
|
|
+ 2. (**Not yet implemented**) If the depending file is a Windows Store app,
|
|
|
+ and the dependency is listed as a dependency in the application's package
|
|
|
+ manifest, the dependency is resolved to that file.
|
|
|
|
|
|
- Lock a file specified by ``<path>`` if no ``DIRECTORY`` option present and
|
|
|
- file ``<path>/cmake.lock`` otherwise. The file will be locked for the scope
|
|
|
- defined by the ``GUARD`` option (default value is ``PROCESS``). The
|
|
|
- ``RELEASE`` option can be used to unlock the file explicitly. If the
|
|
|
- ``TIMEOUT`` option is not specified, CMake will wait until the lock succeeds
|
|
|
- or until a fatal error occurs. If ``TIMEOUT`` is set to ``0``, locking will
|
|
|
- be tried once and the result will be reported immediately. If ``TIMEOUT``
|
|
|
- is not ``0``, CMake will try to lock the file for the period specified by
|
|
|
- the ``TIMEOUT <seconds>`` value. Any errors will be interpreted as fatal if
|
|
|
- there is no ``RESULT_VARIABLE`` option. Otherwise, the result will be stored
|
|
|
- in ``<variable>`` and will be ``0`` on success or an error message on
|
|
|
- failure.
|
|
|
+ 3. Otherwise, if the library exists in the same directory as the depending
|
|
|
+ file, the dependency is resolved to that file.
|
|
|
|
|
|
- Note that lock is advisory; there is no guarantee that other processes will
|
|
|
- respect this lock, i.e. lock synchronize two or more CMake instances sharing
|
|
|
- some modifiable resources. Similar logic applies to the ``DIRECTORY`` option;
|
|
|
- locking a parent directory doesn't prevent other ``LOCK`` commands from
|
|
|
- locking any child directory or file.
|
|
|
+ 4. Otherwise, if the library exists in either the operating system's
|
|
|
+ ``system32`` directory or the ``Windows`` directory, in that order, the
|
|
|
+ dependency is resolved to that file.
|
|
|
|
|
|
- Trying to lock the same file twice is not allowed. Any intermediate
|
|
|
- directories and the file itself will be created if they not exist. The
|
|
|
- ``GUARD`` and ``TIMEOUT`` options are ignored on the ``RELEASE`` operation.
|
|
|
+ 5. Otherwise, if the library exists in one of the directories specified by
|
|
|
+ ``DIRECTORIES``, in the order they are listed, the dependency is resolved
|

|
|
|
+ replacing ``@executable_path/`` with the directory of the executable
|

+ yields an existing file, the dependency is resolved to that file.
|
|
|
|
|
|
- Creates the specified ``<archive>`` file with the files and directories
|
|
|
- listed in ``<paths>``. Note that ``<paths>`` must list actual files or
|
|
|
- directories; wildcards are not supported.
|
|
|
+ 2. Otherwise, if the dependency starts with ``@executable_path/``, and there
|
|
|
+ is a ``BUNDLE_EXECUTABLE`` argument, and replacing ``@executable_path/``
|
|
|
+ with the directory of the bundle executable yields an existing file, the
|
|
|
+ dependency is resolved to that file.
|
|
|
|
|
|
- Use the ``FORMAT`` option to specify the archive format. Supported values
|
|
|
- for ``<format>`` are ``7zip``, ``gnutar``, ``pax``, ``paxr``, ``raw`` and

|
|
- ``zip``. If ``FORMAT`` is not given, the default format is ``paxr``.
|

+ 3. Otherwise, if the dependency starts with ``@loader_path/``, and replacing
|
|
|
+ ``@loader_path/`` with the directory of the depending file yields an
|
|
|
+ existing file, the dependency is resolved to that file.
|
|
|
|
|
|
- Some archive formats allow the type of compression to be specified.
|
|
|
- The ``7zip`` and ``zip`` archive formats already imply a specific type of
|
|
|
- compression. The other formats use no compression by default, but can be
|
|
|
- directed to do so with the ``COMPRESSION`` option. Valid values for
|
|
|
- ``<compression>`` are ``None``, ``BZip2``, ``GZip``, ``XZ``, and ``Zstd``.

+ ``@rpath/`` with one of the ``RPATH`` entries of the depending file
