+Changes made since CMake 3.22 include the following.
+
+* :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.

+ settings and gains the support of ``OBJC``, ``OBJCXX``, ``CUDA``, and ``HIP``
+ languages.

+* :command:`find_package`, :command:`find_program`, :command:`find_library`,
+ :command:`find_path`, and :command:`find_file` now recognize the
+ :variable:`CMAKE_IGNORE_PREFIX_PATH` and
+ :variable:`CMAKE_SYSTEM_IGNORE_PREFIX_PATH` variables.
+
+* :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.

+ level used. These features are available for QtIFW 4.2 and newer.

+ a command after the installer is done if the user accepts the action.
+ This feature is available for QtIFW 4.0 and newer.
+
+* The :cpack_gen:`CPack IFW Generator` gained the new
+ :variable:`CPACK_IFW_PACKAGE_SIGNING_IDENTITY` variable for specifying a code
+ signing identity to be used for signing the generated app bundle.
+ This feature is available on macOS only, and for QtIFW 3.0 and newer.
+
+* The :cpack_gen:`CPack productbuild Generator` gained the new
+ :variable:`CPACK_PRODUCTBUILD_DOMAINS`,
+ :variable:`CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE`,

+ :variable:`CPACK_PRODUCTBUILD_DOMAINS_ROOT` variables for
+ adding the domains element to the Distribution XML.
+
+* The :cpack_gen:`CPack productbuild Generator` gained a new variable,

+ variable, which can be used to specify a timeout for submission inactivity.
+
+* Policy :policy:`CMP0105` and the ``$<DEVICE_LINK:...>`` and

+ are now supported for Clang.
+
+* 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`).
+
+* CUDA compiler detection now correctly handles ``OFF`` for
+ :variable:`CMAKE_CUDA_ARCHITECTURES` on Clang.
+
+* CUDA compiler detection now supports the theoretical case of multiple default
+ architectures.
+
+* CUDA compiler detection now tries to detect invalid architectures and issue
+ an error.

+ `all`, and `all-major` values for CUDA toolkit 7.0+.
+
+* The :variable:`CMAKE_CUDA_ARCHITECTURES` variable now supports the
+ `all`, and `all-major` values for CUDA toolkit 7.0+.

+* ``CUDA`` targets can now enable both :prop_tgt:`CUDA_SEPARABLE_COMPILATION` and
+ :prop_tgt:`CUDA_PTX_COMPILATION`.
+
+* The :command:`define_property` ``BRIEF_DOCS`` and ``FULL_DOCS`` arguments are

+ ``libcufft_static_nocallback``, if found.
+
+* The :module:`FindGLUT` module now provides the ``GLUT_INCLUDE_DIRS``
+ result variable to conform with naming conventions documented in the

+
+* The :module:`FindVulkan` module gained a ``Vulkan_VERSION`` result
+ variable reporting the version number.

+ were added, which list the header file sets associated with a target.
+* New :prop_tgt:`HEADER_SET` and :prop_tgt:`HEADER_SET_<NAME>` properties were
+ added, which list the files in the associated header file set.
+* New :prop_tgt:`HEADER_DIRS` and :prop_tgt:`HEADER_DIRS_<NAME>` properties
+ were added, which specify the base directories of the associated header file
+ set.
+* The :command:`install(TARGETS)` command gained a new ``FILE_SET`` argument,

+ object gained a new installer type of ``fileSet``.
+
+* The :command:`string(TIMESTAMP)` and :command:`file(TIMESTAMP)` commands now
+ support the ``%f`` specifier for microseconds.
+
+* 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.
+ However, this version of CMake does not yet support using
+ :command:`add_custom_command` 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.
+
+* Targets with :prop_tgt:`VS_PACKAGE_REFERENCES` will now automatically attempt
+ to restore the package references from NuGet. The cache variable
+ :variable:`CMAKE_VS_NUGET_PACKAGE_RESTORE` was added to toggle automatic
+ package restore off.

+ command-line option to control automatic package restoration.
+
+* :manual:`cmake-presets(7)` gained support for specifying the
+ ``resolvePackageReferences`` command line option in a build preset.
+

+ was added to tell the :generator:`Xcode` generator what targets to put in
+ the ``Embed PlugIns`` build phase.
+
+* The Xcode project generation learned the variable `XCODE_SCHEME_ENABLE_GPU_FRAME_CAPTURE_MODE` to enable specifying the Xcode scheme option property `GPU Frame Capture`.
