Changes made since CMake 3.30 include the following.
* On AIX, shared libraries may now be created as shared library archives.
See the :variable:`CMAKE_AIX_SHARED_LIBRARY_ARCHIVE` variable
and :prop_tgt:`AIX_SHARED_LIBRARY_ARCHIVE` target property.
New Features
============
* The :prop_tgt:`MACOSX_FRAMEWORK_BUNDLE_NAME <MACOSX_FRAMEWORK_INFO_PLIST>`
target property was added to set the ``CFBundleName`` key in an Apple
:prop_tgt:`FRAMEWORK`'s ``Info.plist`` file.
Presets
-------
* The :variable:`CMAKE_HOST_EXECUTABLE_SUFFIX` variable was added to
provide suffix for executable names on the host platform.
* :manual:`cmake-presets(7)` files may now include comments using the key
``$comment`` at any level within the JSON object to provide documentation.
* :manual:`cmake-presets(7)` files may now request graphviz output using
the ``graphviz`` key in a configure preset.
Generators
----------
* The :ref:`Ninja Generators` and :ref:`Makefile Generators` now produce
a ``codegen`` build target. See policy :policy:`CMP0171`. It drives a
subset of the build graph sufficient to run custom commands created with
:command:`add_custom_command`'s new ``CODEGEN`` option.
Command-Line
------------
* The :option:`cmake --workflow` mode now accepts a preset name as the first
argument, allowing the simpler command line
:option:`cmake --workflow \<preset\> <cmake--workflow --preset>`.
* The :option:`cmake -LR[A][H]` option was added to list cache entries
whose names match a regular expression.
Compilers
---------
* The LFortran compiler is now supported with
:variable:`compiler id <CMAKE_<LANG>_COMPILER_ID>` ``LFortran``.
Commands
--------
* The :command:`add_custom_command` command gained a ``CODEGEN`` option
to mark a custom command's outputs as dependencies of a ``codegen`` target.
See policy :policy:`CMP0171`.
* The :command:`cmake_pkg_config` command was added as an endpoint for using
CMake's native pkg-config format parser. The only supported option in this
release is ``EXTRACT``, which provides low-level access to the values
produced by parsing a pkg-config file. For most users, this is not yet a
suitable replacement for the :module:`FindPkgConfig` module.
* When executing a CMake workflow preset, the ``--preset`` option can now be
omitted, allowing the simpler command line
:option:`cmake --workflow \<preset\> <cmake--workflow --preset>`.
* The :command:`file(ARCHIVE_CREATE)` command gained a ``WORKING_DIRECTORY``
option to specify a working directory for the archiving process.
* The :ref:`Ninja Generators` and :ref:`Makefile Generators` now produce
a ``codegen`` build target. See policy :policy:`CMP0171`. It drives a
subset of the build graph sufficient to run custom commands created with
:command:`add_custom_command`'s new ``CODEGEN`` option.
* The :command:`install(FILES)` and :command:`install(DIRECTORY)` commands'
``TYPE`` argument gained support for a ``LIBEXEC`` type.
* The :command:`add_custom_command` command gained a ``CODEGEN`` option
to mark a custom commands outputs as dependencies of a ``codegen`` target.
Variables
---------
* The :variable:`CMAKE_AIX_SHARED_LIBRARY_ARCHIVE` variable and corresponding
:prop_tgt:`AIX_SHARED_LIBRARY_ARCHIVE` target property were added to
create shared libraries on AIX as shared library archives.
* The :variable:`CMAKE_EXPORT_BUILD_DATABASE` variable, a corresponding
:envvar:`CMAKE_EXPORT_BUILD_DATABASE` environment variable, and an
:prop_tgt:`EXPORT_BUILD_DATABASE` target property, were added to
enable exporting C++ module compile commands.
This is only supported with :ref:`Ninja Generators`.
* The :variable:`CMAKE_HOST_EXECUTABLE_SUFFIX` variable was added to
provide the suffix for executable names on the host platform.
* The :variable:`CMAKE_<LANG>_HOST_COMPILER_ID` and
:variable:`CMAKE_<LANG>_HOST_COMPILER_VERSION` variables were added,
where ``<LANG>`` is either ``CUDA`` or ``HIP``. They are populated
when :variable:`CMAKE_<LANG>_COMPILER_ID` is ``NVIDIA`` to identify
NVCC's host compiler.
* The :variable:`CMAKE_<LANG>_STANDARD_LINK_DIRECTORIES` variable was added.
Toolchain files can set this variable to control which link library directory
paths are always passed to the compiler for the specified language.
* The :variable:`CMAKE_LINK_LIBRARIES_STRATEGY` variable and
corresponding :prop_tgt:`LINK_LIBRARIES_STRATEGY` target
property were added to optionally specify the strategy
CMake uses to generate link lines.
Properties
----------
* The :prop_tgt:`MACOSX_FRAMEWORK_BUNDLE_NAME <MACOSX_FRAMEWORK_INFO_PLIST>`
target property was added to set the ``CFBundleName`` key in an Apple
:prop_tgt:`FRAMEWORK`'s ``Info.plist`` file.
* The :prop_tgt:`UNITY_BUILD` target property now supports the
``CUDA`` language.
* The :prop_tgt:`VS_FRAMEWORK_REFERENCES` target property was added
to tell :ref:`Visual Studio Generators` to add framework references.
Modules
-------
* Check modules now support a ``CMAKE_REQUIRED_LINK_DIRECTORIES`` variable.
The following modules gained this support:
* :module:`CMakePushCheckState`
* :module:`CheckCCompilerFlag`
* :module:`CheckCSourceCompiles`
* :module:`CheckCSourceRuns`

:command:`generate_apple_platform_selection_file` function
gained support for iOS Mac Catalyst.
* The :module:`GoogleTest` module :command:`gtest_discover_tests` command
gained a new ``DISCOVERY_EXTRA_ARGS`` keyword. It allows extra arguments
to be appended to the command line when querying for the list of tests.
* The :module:`FindCUDAToolkit` module now provides a ``CUDA::nvml_static``
target.
* The :module:`FindOpenMP` module gained support for the ``CUDA`` language.
CTest
-----
* The :command:`ctest_submit` command and :option:`ctest -T Submit <ctest -T>`
step now verify TLS server certificates for connections to ``https://`` URLs
by default. See the :variable:`CTEST_TLS_VERIFY` variable for details.
* The :command:`ctest_submit` command and :option:`ctest -T Submit <ctest -T>`
step now require TLS 1.2 or higher for connections to ``https://`` URLs by
default. See the :variable:`CTEST_TLS_VERSION` variable for details.

Deprecated and Removed Features
===============================
* The :module:`FindCUDAToolkit` module now provides a ``CUDA::nvml_static``
target.
* Compatibility with versions of CMake older than 3.10 is now deprecated
and will be removed from a future version. Calls to
:command:`cmake_minimum_required` or :command:`cmake_policy` that set
the policy version to an older value now issue a deprecation diagnostic.
* The :module:`CMakeFindFrameworks` module has been deprecated via
:policy:`CMP0173`. Projects should use :command:`find_library` instead.
* The :generator:`Visual Studio 12 2013` generator has been removed.
Other Changes
=============
* When static libraries on link lines are de-duplicated (by policy
:policy:`CMP0156`), the first occurrence is now kept on all platforms.
See policy :policy:`CMP0179`.
