|
+Changes made since CMake 3.10 include the following.
|
|
|
+
|
|
|
+New Features
|
|
|
+============
|
|
|
+
|
|
|
+Platforms
|
|
|
+---------
|
|
|
+
|
|
|
+* TI C/C++ compilers are now supported by the :generator:`Ninja` generator.
|
|
|
+
|
|
|
+Generators
|
|
|
+----------
|
|
|
+
|
|
|
+* The :generator:`CodeBlocks` extra generator learned to check a
|
|
|
+ :variable:`CMAKE_CODEBLOCKS_COMPILER_ID` variable for a custom
|
|
|
+ compiler identification value to place in the project file.
|
|
|
+
|
|
|
+* The :ref:`Makefile Generators` and the :generator:`Ninja` generator learned
|
|
|
+ to add compiler launcher tools along with the compiler for the ``Fortran``
|
|
|
+ language (``C``, ``CXX``, and ``CUDA`` were supported previously).
|
|
|
+ See the :variable:`CMAKE_<LANG>_COMPILER_LAUNCHER` variable and
|
|
|
+ :prop_tgt:`<LANG>_COMPILER_LAUNCHER` target property for details.
|
|
|
+
|
|
|
+* :ref:`Visual Studio Generators` learned to support the ``COMPILE_LANGUAGE``
|
|
|
+ :manual:`generator expression <cmake-generator-expressions(7)>` in
|
|
|
+ target-wide :prop_tgt:`COMPILE_DEFINITIONS`,
|
|
|
+ :prop_tgt:`INCLUDE_DIRECTORIES`, :prop_tgt:`COMPILE_OPTIONS`, and
|
|
|
+ :command:`file(GENERATE)`. See generator expression documentation
|
|
|
+ for caveats.
|
|
|
+
|
|
|
+* The :generator:`Xcode` generator learned to support the ``COMPILE_LANGUAGE``
|
|
|
+ :manual:`generator expression <cmake-generator-expressions(7)>` in
|
|
|
+ target-wide :prop_tgt:`COMPILE_DEFINITIONS` and
|
|
|
+ :prop_tgt:`INCLUDE_DIRECTORIES`. It previously supported only
|
|
|
+ :prop_tgt:`COMPILE_OPTIONS` and :command:`file(GENERATE)`.
|
|
|
+ See generator expression documentation for caveats.
|
|
|
+
|
|
|
+Commands
|
|
|
+--------
|
|
|
+
|
|
|
+* :command:`add_library` and :command:`add_executable` commands can now be
|
|
|
+ called without any sources and will not complain as long as sources are
|
|
|
+ added later via the :command:`target_sources` command.
|
|
|
+
|
|
|
+* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands
|
|
|
+ gained ``NETRC`` and ``NETRC_FILE`` options to specify use of a
|
|
|
+ ``.netrc`` file.
|
|
|
+
|
|
|
+* The :command:`target_compile_definitions` command learned to set the
|
|
|
+ :prop_tgt:`INTERFACE_COMPILE_DEFINITIONS` property on
|
|
|
+ :ref:`Imported Targets`.
|
|
|
+
|
|
|
+* The :command:`target_compile_features` command learned to set the
|
|
|
+ :prop_tgt:`INTERFACE_COMPILE_FEATURES` property on :ref:`Imported Targets`.
|
|
|
+
|
|
|
+* The :command:`target_compile_options` command learned to set the
|
|
|
+ :prop_tgt:`INTERFACE_COMPILE_OPTIONS` property on :ref:`Imported Targets`.
|
|
|
+
|
|
|
+* The :command:`target_include_directories` command learned to set the
|
|
|
+ :prop_tgt:`INTERFACE_INCLUDE_DIRECTORIES` property on
|
|
|
+ :ref:`Imported Targets`.
|
|
|
+
|
|
|
+* The :command:`target_sources` command learned to set the
|
|
|
+ :prop_tgt:`INTERFACE_SOURCES` property on :ref:`Imported Targets`.
|
|
|
+
|
|
|
+* The :command:`target_link_libraries` command learned to set the
|
|
|
+ :prop_tgt:`INTERFACE_LINK_LIBRARIES` property on :ref:`Imported Targets`.
|
|
|
+
|
|
|
+Variables
|
|
|
+---------
|
|
|
+
|
|
|
+* A :variable:`CMAKE_GENERATOR_INSTANCE` variable was introduced
|
|
|
+ to hold the selected instance of the generator's corresponding
|
|
|
+ native tools if multiple are available. This is used by the
|
|
|
+ :generator:`Visual Studio 15 2017` generator to hold the
|
|
|
+ selected instance of Visual Studio persistently.
|
|
|
+
|
|
|
+* A :variable:`CMAKE_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS` variable was added
|
|
|
+ to enable setting of default permissions for directories created implicitly
|
|
|
+ during installation of files by :command:`install` and
|
|
|
+ :command:`file(INSTALL)`, e.g. during ``make install``.
|
|
|
+
|
|
|
+* A :variable:`CMAKE_JOB_POOLS` variable was added specify a value to use for
|
|
|
+ the :prop_gbl:`JOB_POOLS` property. This enables control over build
|
|
|
+ parallelism with command line configuration parameters when using the Ninja
|
|
|
+ generator.
|
|
|
+
|
|
|
+* The :variable:`CMAKE_NETRC` and :variable:`CMAKE_NETRC_FILE` variables
|
|
|
+ were added to specify use of a ``.netrc`` file by the
|
|
|
+ :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands and
|
|
|
+ the :module:`ExternalProject` module.
|
|
|
+
|
|
|
+* A :variable:`CMAKE_CUDA_SEPARABLE_COMPILATION` variable was added to
|
|
|
+ initialize the :prop_tgt:`CUDA_SEPARABLE_COMPILATION` target property
|
|
|
+ on targets when they are created.
|
|
|
+
|
|
|
+Properties
|
|
|
+----------
|
|
|
+
|
|
|
+* The :prop_sf:`COMPILE_DEFINITIONS` source file property learned to support
|
|
|
+ :manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
+
|
|
|
+* A :prop_sf:`COMPILE_OPTIONS` source file property was added to manage list
|
|
|
+ of options to pass to the compiler.
|
|
|
+
|
|
|
+* An :prop_tgt:`IMPORTED_GLOBAL` target property was added to indicate
|
|
|
+ whether an :ref:`IMPORTED target <Imported Targets>` is globally visible.
|
|
|
+ It is automatically set to a true value for targets created with the
|
|
|
+ ``GLOBAL`` option to :command:`add_library` or :command:`add_executable`.
|
|
|
+ Additionally, project code may now *promote* a local imported target
|
|
|
+ to be globally visible by setting this property to ``TRUE``.
|
|
|
+
|
|
|
+* An :prop_sf:`INCLUDE_DIRECTORIES` source file property was added to specify
|
|
|
+ list of preprocessor include file search directories.
|
|
|
+
|
|
|
+* Source file properties :prop_sf:`VS_SHADER_DISABLE_OPTIMIZATIONS` and
|
|
|
+ :prop_sf:`VS_SHADER_ENABLE_DEBUG` have been added to specify more
|
|
|
+ details of ``.hlsl`` sources with :ref:`Visual Studio Generators`.
|
|
|
+
|
|
|
+Modules
|
|
|
+-------
|
|
|
+
|
|
|
+* The :module:`CheckIncludeFile` module ``check_include_file`` macro
|
|
|
+ learned to honor the ``CMAKE_REQUIRED_LIBRARIES`` variable.
|
|
|
+
|
|
|
+* The :module:`CheckIncludeFileCXX` module ``check_include_file_cxx`` macro
|
|
|
+ learned to honor the ``CMAKE_REQUIRED_LIBRARIES`` variable.
|
|
|
+
|
|
|
+* The :module:`CheckIncludeFiles` module ``check_include_files`` macro
|
|
|
+ learned to honor the ``CMAKE_REQUIRED_LIBRARIES`` variable.
|
|
|
+
|
|
|
+* The :module:`CheckIncludeFiles` module :command:`CHECK_INCLUDE_FILES`
|
|
|
+ command gained a ``LANGUAGE`` option to specify whether to check using the
|
|
|
+ ``C`` or ``CXX`` compiler.
|
|
|
+
|
|
|
+* The :module:`CMakePackageConfigHelpers` module
|
|
|
+ :command:`write_basic_package_version_file` command learned a new
|
|
|
+ ``SameMinorVersion`` mode for the ``COMPATIBILITY`` argument.
|
|
|
+
|
|
|
+* The :module:`ExternalProject` module learned to substitute ``<DOWNLOAD_DIR>``
|
|
|
+ in comments, commands, working directory and byproducts.
|
|
|
+
|
|
|
+* The :module:`ExternalProject` module gained ``NETRC`` and ``NETRC_FILE``
|
|
|
+ options to specify use of a ``.netrc`` file.
|
|
|
+
|
|
|
+* A new :module:`FetchContent` module was added which supports populating
|
|
|
+ content at configure time using any of the download/update methods
|
|
|
+ supported by :command:`ExternalProject_Add`. This allows the content
|
|
|
+ to be used immediately during the configure stage, such as with
|
|
|
+ :command:`add_subdirectory`, etc. Hierarchical project structures are
|
|
|
+ well supported, allowing parent projects to override the content details
|
|
|
+ of child projects and ensuring content is not populated multiple times
|
|
|
+ throughout the whole project tree.
|
|
|
+
|
|
|
+* The :module:`FindBLAS` and :module:`FindLAPACK` modules learned to support
|
|
|
+ `FLAME`_ ``blis`` and ``libflame``.
|
|
|
+
|
|
|
+* The :module:`FindDoxygen` module :command:`doxygen_add_docs` function
|
|
|
+ now supports a new ``DOXYGEN_VERBATIM_VARS`` list variable. Any
|
|
|
+ ``DOXYGEN_...`` variable contained in that list will bypass the automatic
|
|
|
+ quoting logic, leaving its contents untouched when transferring them to the
|
|
|
+ output ``Doxyfile``.
|
|
|
+
|
|
|
+* A :module:`FindIconv` module was added to locate iconv support.
|
|
|
+
|
|
|
+* The :module:`GenerateExportHeader` module ``GENERATE_EXPORT_HEADER`` command
|
|
|
+ gained an ``INCLUDE_GUARD_NAME`` option to change the name of the include
|
|
|
+ guard symbol written to the generated export header.
|
|
|
+ Additionally, it now adds a comment after the closing ``#endif`` on the
|
|
|
+ generated export header's include guard.
|
|
|
+
|
|
|
+* The :module:`UseJava` module ``add_jar`` command gained a
|
|
|
+ ``GENERATE_NATIVE_HEADERS`` option to generate native header files
|
|
|
+ using ``javac -h`` for ``javac`` 1.8 or above. This supersedes
|
|
|
+ ``create_javah``, which no longer works with JDK 1.10 and above due
|
|
|
+ to removal of the ``javah`` tool by `JEP 313`_.

|
|
|
+
|
|
|
+Autogen
|
|
|
+-------
|
|
|
+
|
|
|
+* When using :prop_tgt:`AUTOMOC` or :prop_tgt:`AUTOUIC`, CMake now starts
|
|
|
+ multiple parallel ``moc`` or ``uic`` processes to reduce the build time.
|
|
|
+ A new :variable:`CMAKE_AUTOGEN_PARALLEL` variable and
|
|
|
+ :prop_tgt:`AUTOGEN_PARALLEL` target property may be set to specify the
|
|
|
+ number of parallel ``moc`` or ``uic`` processes to start. The default
|
|
|
+ is derived from the number of CPUs on the host.
|
|
|
+
|
|
|
+CTest
|
|
|
+-----
|
|
|
+
|
|
|
+* The :command:`ctest_start` command no longer sets
|
|
|
+ :variable:`CTEST_RUN_CURRENT_SCRIPT` due to issues with scoping if it is
|
|
|
+ called from inside a function. Instead, it sets an internal variable in
|
|
|
+ CTest. However, setting :variable:`CTEST_RUN_CURRENT_SCRIPT` to 0 at the
|
|
|
+ global scope still prevents the script from being re-run at the end.
|
|
|
+
|
|
|
+CPack
|
|
|
+-----
|
|
|
+
|
|
|
+* :manual:`cpack(1)` gained ``--trace`` and ``--trace-expand`` options.
|
|
|
+
|
|
|
+* The :module:`CPackIFW` module gained new
|
|
|
+ :variable:`CPACK_IFW_PACKAGE_REMOVE_TARGET_DIR` variable to control
|
|
|
+ if the target directory should not be deleted when uninstalling.
|
|
|
+
|
|
|
+* The :module:`CPackRPM` module learned to enable enforcing of execute
|
|
|
+ privileges on programs and shared libraries.
|
|
|
+ See :variable:`CPACK_RPM_INSTALL_WITH_EXEC` variable.
|
|
|
+
|
|
|
+* A :variable:`CPACK_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS` variable was added
|
|
|
+ which serves the same purpose during packaging (e.g. ``make package``) as the
|
|
|
+ :variable:`CMAKE_INSTALL_DEFAULT_DIRECTORY_PERMISSIONS` variable serves during
|
|
|
+ installation (e.g. ``make install``).
|
|
|
+
|
|
|
+Other
|
|
|
+-----
|
|
|
+
|
|
|
+* :ref:`Alias Targets` may now alias :ref:`Imported Targets` that are
|
|
|
+ created with the ``GLOBAL`` option to :command:`add_library`.
|
|
|
+
|
|
|
+* :ref:`Interface Libraries` may now have custom properties set on them if
|
|
|
+ they start with either an underscore (``_``) or a lowercase ASCII character.
|
|
|
+ The original intention was to only allow properties which made sense for
|
|
|
+ ``INTERFACE`` libraries, but it also blocked usage of custom properties.
|
|
|
+
|
|
|
+* The :manual:`cmake(1)` ``--open <dir>`` command-line option was added
|
|
|
+ to open generated IDE projects like Visual Studio solutions or Xcode
|
|
|
+ projects.
|
|
|
+
|
|
|
+Deprecated and Removed Features
|
|
|
+===============================
|
|
|
+
|
|
|
+* An explicit deprecation diagnostic was added for policies ``CMP0037``
|
|
|
+ through ``CMP0054`` (``CMP0036`` and below were already deprecated).
|
|
|
+ The :manual:`cmake-policies(7)` manual explains that the OLD behaviors
|
|
|
+ of all policies are deprecated and that projects should port to the
|
|
|
+ NEW behaviors.
|
|
|
+
|
|
|
+* The ``KDevelop3`` generator has been removed.
|
|
|
+
|
|
|
+Other Changes
|
|
|
+=============
|
|
|
+
|
|
|
+* Policy :policy:`CMP0037` no longer reserves target names associated
|
|
|
+ with optional features, such as ``test`` and ``package``, unless
|
|
|
+ the corresponding feature is enabled.
|
|
|
+
|
|
|
+* The :module:`FindOpenGL` module now prefers GLVND libraries if available.
|
|
|
+ See policy :policy:`CMP0072`.
|
|
|
+
|
|
|
+* The minimum deployment target set in the
|
|
|
+ :variable:`CMAKE_OSX_DEPLOYMENT_TARGET` variable used to be only
|
|
|
+ applied for macOS regardless of the selected SDK. It is now properly
|
|
|
+ set for the target platform selected by :variable:`CMAKE_OSX_SYSROOT`.
|
|
|
+ For example, if the sysroot variable specifies an iOS SDK then the
|
|
|
+ value in ``CMAKE_OSX_DEPLOYMENT_TARGET`` is interpreted as minimum
|
|
|
+ iOS version.
|
|
|
+
|
|
|
+* The :generator:`Xcode` generator behavior of generating one project
|
|
|
+ file per :command:`project()` command may now be controlled with the
|
|
|
+ :variable:`CMAKE_XCODE_GENERATE_TOP_LEVEL_PROJECT_ONLY` variable.
|
|
|
+ This could be useful to speed up the CMake generation step for
|
|
|
+ large projects and to work-around a bug in the ``ZERO_CHECK`` logic.
|
|
|
+
|
|
|
+* Since the ``CMakeCache.txt`` format does not support newlines in values,
|
|
|
+ values containing newlines are now truncated before writing to the file.
|
|
|
+ In addition, a warning comment is written to the cache file, and a warning
|
|
|
+ message is displayed to the user on the console.
