|
|
+Changes made since CMake 3.22 include the following.
|
|
|
+
|
|
|
+New Features
|
|
|
+============
|
|
|
+
|
|
|
+Presets
|
|
|
+-------
|
|
|
+
|
|
|
+* :manual:`cmake-presets(7)` files now support schema version ``4``.
|
|
|
+
|
|
|
+* :manual:`cmake-presets(7)` files now have an optional ``include`` field,
|
|
|
+ which allows the files to include other files.
|
|
|
+
|
|
|
+* :manual:`cmake-presets(7)` gained support for specifying the
|
|
|
+ ``resolvePackageReferences`` command line option in a build preset.
|
|
|
+
|
|
|
+Generators
|
|
|
+----------
|
|
|
+
|
|
|
+* The :ref:`Visual Studio Generators` for VS 2019 and above learned to
|
|
|
+ support .NET SDK-style project files (``.csproj``) for C# projects.
|
|
|
+ See the :prop_tgt:`DOTNET_SDK` target property and corresponding
|
|
|
+ :variable:`CMAKE_DOTNET_SDK` variable. :command:`add_custom_command`
|
|
|
+ is not yet supported in .NET SDK-style projects.
|
|
|
+
|
|
|
+* The :ref:`Visual Studio Generators` for VS 2017 and above learned to
|
|
|
+ use portable instances of Visual Studio not known to the VS installer.
|
|
|
+ See the :variable:`CMAKE_GENERATOR_INSTANCE` variable.
|
|
|
+
|
|
|
+Command-Line
|
|
|
+------------
|
|
|
+
|
|
|
+* The :manual:`cmake(1)` ``--build`` command, when used with
|
|
|
+ :ref:`Visual Studio Generators` on projects that set the
|
|
|
+ :prop_tgt:`VS_PACKAGE_REFERENCES` target property, now automatically
|
|
|
+ restores package references from NuGet. The cache variable
|
|
|
+ :variable:`CMAKE_VS_NUGET_PACKAGE_RESTORE` may be set to toggle this behavior
|
|
|
+ in a build tree. Use the ``--resolve-package-references=<on|off|only>``
|
|
|
+ command-line option to control the behavior on one invocation.
|
|
|
+
|
|
|
+* The :manual:`cmake(1)` command line tool gained a ``--debug-find-pkg=``
|
|
|
+ option to enable debug messages under specific :command:`find_package`
|
|
|
+ calls.
|
|
|
+
|
|
|
+* The :manual:`cmake(1)` command line tool gained a ``--debug-find-var=``
|
|
|
+ option to enable debug messages for ``find_*`` calls that use specific
|
|
|
+ result variables.
|
|
|
+
|
|
|
+Compilers
|
|
|
+---------
|
|
|
+
|
|
|
+* The IBM Open XL C/C++ compiler, based on LLVM, is now supported with
|
|
|
+ compiler id ``IBMClang``.
|
|
|
+
|
|
|
+* The MCST LCC compiler is now supported with compiler id ``LCC``.
|
|
|
+ See policy :policy:`CMP0129`.
|
|
|
+
|
|
|
+File-Based API
|
|
|
+--------------
|
|
|
+
|
|
|
+* The :manual:`cmake-file-api(7)` "codemodel" version 2 ``version`` field
|
|
|
+ has been updated to ``2.4``.
|
|
|
+
|
|
|
+* The :manual:`cmake-file-api(7)` "codemodel" version 2 ``directory``
|
|
|
+ object ``installers`` field gained a new ``fileSet`` installer type.
|
|
|
+
|
|
|
+Commands
|
|
|
+--------
|
|
|
+
|
|
|
+* The :command:`define_property` command gained a new
|
|
|
+ ``INITIALIZE_FROM_VARIABLE`` option to cause a target property to be
|
|
|
+ initialized from a variable when a target is created.
|
|
|
+
|
|
|
+* The :command:`install(TARGETS)` command gained a new ``FILE_SET`` argument,
|
|
|
+ which can be used to install header file sets associated with a target.
|
|
|
+
|
|
|
+* The :command:`string(TIMESTAMP)` and :command:`file(TIMESTAMP)` commands now
|
|
|
+ support the ``%f`` specifier for microseconds.
|
|
|
+
|
|
|
+* The :command:`target_sources` command gained a new ``FILE_SET`` mode, which
|
|
|
+ can be used to add headers as header-only source files of a target.
|
|
|
+
|
|
|
+Variables
|
|
|
+---------
|
|
|
+
|
|
|
+* The :variable:`CMAKE_CUDA_ARCHITECTURES` variable and associated
|
|
|
+ :prop_tgt:`CUDA_ARCHITECTURES` target property now support the
|
|
|
+ ``all``, and ``all-major`` values for CUDA toolkit 7.0+.
|
|
|
+
|
|
|
+* The :variable:`CMAKE_IGNORE_PREFIX_PATH` and
|
|
|
+ :variable:`CMAKE_SYSTEM_IGNORE_PREFIX_PATH` variables were added
|
|
|

|
|
|
+ commands to ignore specified prefixes.
|
|
|
+
|
|
|
+* The :variable:`CMAKE_LINK_LIBRARIES_ONLY_TARGETS` variable and
|
|
|
+ corresponding :prop_tgt:`LINK_LIBRARIES_ONLY_TARGETS` target
|
|
|
+ property were added to optionally require that all link items
|
|
|
+ that can be target names are actually names of existing targets.

+
|
|
|

|
|
|
+
|
|
|
+* The :prop_tgt:`IMPORTED_NO_SYSTEM` target property was added to
|
|
|
+ specify that an :ref:`Imported Target <Imported Targets>` should
|
|
|
+ not be treated as a system library (i.e. its include directories
|
|
|
+ are not automatically ``SYSTEM``).
|
|

|
|
|
+
|
|
|
+Deprecated and Removed Features
|
|
|
+===============================
|
|
|
+
|
|
|
+* The :manual:`cpack(1)` undocumented ``OSXX11`` generator has been removed.
|
|
|
+
|
|
|
+Other Changes
|
|
|
+=============
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack DragNDrop Generator` no longer attaches
|
|
|
+ :variable:`CPACK_RESOURCE_FILE_LICENSE` as the license agreement in
|
|
|
+ the generated ``.dmg`` unless explicitly activated by a
|
|
|
+ :variable:`CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` option.
|
|
|
+ In CMake projects, the :module:`CPack` module enables the option
|
|
|
+ by default for compatibility.
|
|
|
+
|
|
|
+* ``CUDA`` targets may now enable both :prop_tgt:`CUDA_SEPARABLE_COMPILATION`
|
|
|
+ and :prop_tgt:`CUDA_PTX_COMPILATION`.
|
|
|
+
|
|
|
+* ``CUDA`` compiler detection now:
|
|
|
+
|
|
|
+ * issues an error in all cases when it's unable to compute the default
|
|
|
+ architecture(s) if required (see :policy:`CMP0104`),
|
|
|
+
|
|
|
+ * handles ``OFF`` for :variable:`CMAKE_CUDA_ARCHITECTURES` on Clang,
|
|
|
+
|
|
|
+ * supports the theoretical case of multiple default architectures, and
|
|
|
+
|
|
|
+ * tries to detect invalid architectures and issue an error.
|
|
|
+
|
|
|
+* ``CUDA`` with Clang now implements policy :policy:`CMP0105` and
|
|
|
+ the ``$<DEVICE_LINK:...>`` and ``$<HOST_LINK:...>``
|
|
|
+ :manual:`generator expressions <cmake-generator-expressions(7)>`.
|
|
|
+
|
|
|
+* The :command:`define_property` command's ``BRIEF_DOCS`` and ``FULL_DOCS``
|
|
|
+ arguments are now optional.
|
|
|
+
|
|
|
+* :manual:`ccmake(1)` may now be enabled on Windows when building
|
|
|
+ CMake from source. This is experimental, and so is not included
|
|
|
+ in official distributions.
