|
|
|
+Changes made since CMake 3.21 include the following.
|
|
|
+
|
|
|
+* The :module:`CMakeDependentOption` module :command:`cmake_dependent_option`
|
|
|
+ macro now supports full :ref:`Condition Syntax`.
|
|
|
+ See policy :policy:`CMP0127`.
|
|
|
+
|
|
|
+* The :envvar:`CMAKE_INSTALL_MODE` environment variable was added to
|
|
|
+ allow users to override the default file-copying behavior of
|
|
|
+ :command:`install` and :command:`file(INSTALL)` into creating
|
|
|
+ symbolic links. This can aid in lowering storage space requirements
|
|
|
+ and avoiding redundancy.
|
|
|
+
|
|
|
+* The :command:`file(INSTALL)` can now be affected / modified by the
|
|
|
+ :envvar:`CMAKE_INSTALL_MODE` environment variable causing installation
|
|
|
+ of symbolic links instead of copying of files.
|
|
|
+
|
|
|
+* The :command:`install` can now be affected / modified by the
|
|
|
+ :envvar:`CMAKE_INSTALL_MODE` environment variable causing installation
|
|
|
+ of symbolic links instead of copying of files.
|
|
|
+
|
|
|
+* The :manual:`Compile Features <cmake-compile-features(7)>` functionality now
|
|
|
+ correctly disables or enables compiler extensions when no standard level is
|
|
|
+ specified and avoids unnecessarily adding language standard flags if the
|
|
|
+ requested settings match the compiler's defaults. See :policy:`CMP0128`.
|
|
|
+
|
|
|
+* :prop_tgt:`<LANG>_EXTENSIONS` is initialized to
|
|
|
+ :variable:`CMAKE_<LANG>_EXTENSIONS_DEFAULT`. See :policy:`CMP0128`.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack DEB Generator` gained the
|
|
|
+ option to set :variable:`CPACK_DEBIAN_COMPRESSION_TYPE` to zstd,
|
|
|
+ which enables Zstandard compression for deb packages.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack RPM Generator` gained the
|
|
|
+ :variable:`CPACK_RPM_REQUIRES_EXCLUDE_FROM` option avoid scanning
|
|
|
+ specific paths for dependencies.
|
|
|
+
|
|
|
+* :manual:`ctest(1)` learned to be able to modify the environment for a test
|
|
|
+ through the :prop_test:`ENVIRONMENT_MODIFICATION` property. This is allows
|
|
|
+ for updates to environment variables based on the environment present at
|
|
|
+ test time.
|
|
|
+
|
|
|
+* The :command:`ctest_memcheck` command now also generates a
|
|
|
+ `DynamicAnalysis-Test.xml` file which may be used to submit test results to
|
|
|
+ CDash.
|
|
|
+
|
|
|
+* :manual:`ctest(1)` learned to recognize labels attached to a test at run time.
|
|
|
+ Previously it was only possible to attach labels to tests at configure time
|
|
|
+ by using the :prop_test:`LABELS` test property.
|
|
|
+ See :ref:`Additional Test Measurements` for more information.
|
|
|
+
|
|
|
+* The :envvar:`CMAKE_BUILD_TYPE` environment variable was added to
|
|
|
+ provide a default value for the :variable:`CMAKE_BUILD_TYPE` variable.
|
|
|
+
|
|
|
+* The :envvar:`CMAKE_CONFIGURATION_TYPES` environment variable was added to
|
|
|
+ provide a default value for the :variable:`CMAKE_CONFIGURATION_TYPES`
|
|
|
+ variable.
|
|
|
+
|
|
|
+* The :module:`FetchContent` module now passes through the
|
|
|
+ :variable:`CMAKE_TLS_VERIFY`, :variable:`CMAKE_TLS_CAINFO`,
|
|
|
+ :variable:`CMAKE_NETRC` and :variable:`CMAKE_NETRC_FILE` variables (when
|
|
|
+ defined) to the underlying :module:`ExternalProject` sub-build.
|
|
|
+ Previously, those variables were silently ignored by :module:`FetchContent`.
|
|
|
+
|
|
|
+* The :module:`FindBLAS` and :module:`FindLAPACK` modules gained
|
|
|
+ a ``BLA_SIZEOF_INTEGER`` option to find a BLAS/LAPACK whose ABI
|
|
|
+ uses a specific integer size.
|
|
|
+
|
|
|
+* The :module:`FindJasper` module now provides an imported target.
|
|
|
+
|
|
|
+* The :module:`FindMatlab` module now provides imported targets.
|
|
|
+
|
|
|
+* The :variable:`CMAKE_REQUIRE_FIND_PACKAGE_<PackageName>` variable was added
|
|
|
+ to turn a non-REQUIRED :command:`find_package` call into a REQUIRED one.
|
|
|
+
|
|
|
+* The :module:`FindPkgConfig` module gained a :variable:`PKG_CONFIG_ARGN`
|
|
|
+ variable to specify arguments to ``pkg-config`` calls.
|
|
|
+
|
|
|
+* The :module:`GoogleTest` module :command:`gtest_discover_tests`
|
|
|
+ function gained a ``TEST_FILTER`` option to filter tests using
|
|
|
+ ``--gtest_filter`` during test discovery.
|
|
|
+
|
|
|
+* Configuration for :prop_tgt:`LINK_WHAT_YOU_USE` feature is now controlled by
|
|
|
+ ``CMake`` variables and only active for ``ELF`` platforms.
|
|
|
+
|
|
|
+* The MSVC compilers learned to pass the ``-external:I`` flag for system
|
|
|
+ includes when using the :generator:`Ninja` and :generator:`NMake Makefiles`
|
|
|
+ generators. This became available as of Visual Studio 16.10 (toolchain
|
|
|
+ version 14.29.30037).
|
|
|
+
|
|
|
+* The :ref:`Ninja Generators` now implement the ``edit_cache`` target
|
|
|
+ using :manual:`ccmake(1)` if available.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack NSIS Generator` gained a new variable
|
|
|
+ :variable:`CPACK_NSIS_IGNORE_LICENSE_PAGE` to ignore the
|
|
|
+ license page in the installer.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack NSIS Generator` now requires NSIS 3.03 or later.
|
|
|
+
|
|
|
+* The :command:`cmake_host_system_information` command query operating system
|
|
|
+ identification `variables <https://www.freedesktop.org/software/systemd/man/os-release.html>`_
|
|
|
+ from the :file:`/etc/os-release` file.
|
|
|
+
|
|
|
+* The :command:`string(TIMESTAMP)` command now supports the ``%V``
|
|
|
+ specifier for ISO 8601 week numbers.
|
|
|
+
|
|
|
+* :command:`target_compile_features` learned to ignored features for languages that
|
|
|
+ aren't enabled.
|
|
|
+
|
|
|
+* :module:`UseSWIG` module gained the capability, for
|
|
|
+ :ref:`Visual Studio Generators` to use `swig` tool to generate implicit
|
|
|
+ dependencies.
|
|
|
+
|
|
|
+* The :generator:`Visual Studio 10 2010` generator is now deprecated
|
|
|
+ and will be removed in a future version of CMake.
|
|
|
+
|
|
|
+* The :prop_sf:`VS_SETTINGS` source file property is now supported for
|
|
|
+ all source file types. Previously it worked only for non-built sources.
