|
|
|
+Changes made since CMake 3.29 include the following.
|
|
|
+
|
|
|
+New Features
|
|
|
+============
|
|
|
+
|
|
|
+Presets
|
|
|
+-------
|
|
|
+
|
|
|
+* :manual:`cmake-presets(7)` files now support schema version ``9``.
|
|
|
+ ``include`` fields now expand all macros except ``$env{}`` and
|
|
|
+ preset-specific macros.
|
|
|
+
|
|
|
+File-Based API
|
|
|
+--------------
|
|
|
+
|
|
|
+* The :manual:`cmake-file-api(7)` "cmakeFiles" version 1 object's ``version``
|
|
|
+ field has been updated to 1.1. It gained a ``globsDependent`` field to
|
|
|
+ report :command:`file(GLOB)` calls using ``CONFIGURE_DEPENDS``.
|
|
|
+
|
|
|
+Generators
|
|
|
+----------
|
|
|
+
|
|
|
+* :ref:`Visual Studio Generators` now add ``UseDebugLibraries`` indicators to
|
|
|
+ ``.vcxproj`` files to denote which configurations are debug configurations.
|
|
|
+ See policy :policy:`CMP0162`.
|
|
|
+
|
|
|
+Languages
|
|
|
+---------
|
|
|
+
|
|
|
+* The :manual:`Compile Features <cmake-compile-features(7)>` functionality
|
|
|
+ now implements support for the ``cxx_std_26`` and ``cuda_std_26``
|
|
|
+ meta-features to indicate that the compiler mode must be at least C++26.
|
|
|
+ These meta-features were first documented by CMake 3.25, but were not fully
|
|
|
+ implemented.
|
|
|
+
|
|
|
+Commands
|
|
|
+--------
|
|
|
+
|
|
|
+* The :command:`add_library` command, on platforms that do not support shared
|
|
|
+ libraries, now rejects creation of shared libraries instead of automatically
|
|
|
+ converting them to static libraries. See policy :policy:`CMP0164`.
|
|
|
+
|
|
|
+* The :command:`enable_language` command now fails with an error
|
|
|
+ if it is called before the first :command:`project` call.
|
|
|
+ See policy :policy:`CMP0165`.
|
|
|
+
|
|
|
+* The :command:`file(DOWNLOAD)` and :command:`file(UPLOAD)` commands
|
|
|
+ gained a ``TLS_VERSION <min>`` option to specify the minimum TLS
|
|
|
+ version for connections to ``https://`` URLs.
|
|
|
+
|
|
|
+Variables
|
|
|
+---------
|
|
|
+
|
|
|
+* The :variable:`CMAKE_<LANG>_STANDARD_LATEST` variable was added to
|
|
|
+ describe the latest ``<LANG>`` language standard CMake supports for
|
|
|
+ the selected compiler.
|
|
|
+
|
|
|
+* The :envvar:`CMAKE_TLS_VERIFY` environment variable was added as a fallback
|
|
|
+ to the existing :variable:`CMAKE_TLS_VERIFY` variable. It specifies
|
|
|
+ whether to verify the server certificate for ``https://`` URLs by default.
|
|
|
+
|
|
|
+* The :variable:`CMAKE_TLS_VERSION` variable and :envvar:`CMAKE_TLS_VERSION`
|
|
|
+ environment variable were added to specify a default minimum TLS version
|
|
|
+ for connections to ``https://`` URLs by the :command:`file(DOWNLOAD)`
|
|
|
+ and :command:`file(UPLOAD)` commands.
|
|
|
+
|
|
|
+* The :variable:`CMAKE_VS_USE_DEBUG_LIBRARIES` variable and corresponding
|
|
|
+ :prop_tgt:`VS_USE_DEBUG_LIBRARIES` target property were added to explicitly
|
|
|
+ control ``UseDebugLibraries`` indicators in ``.vcxproj`` files.
|
|
|
+
|
|
|
+Properties
|
|
|
+----------
|
|
|
+
|
|
|
+* The :prop_sf:`GENERATED` source file property is now visible in all
|
|
|
+ directories. See policy :policy:`CMP0163`. Policy :policy:`CMP0118`'s
|
|
|
+ documentation has been revised to describe its actual effects.
|
|
|
+
|
|
|
+* The :prop_gbl:`PROPAGATE_TOP_LEVEL_INCLUDES_TO_TRY_COMPILE` global property
|
|
|
+ can be used to propagate :variable:`CMAKE_PROJECT_TOP_LEVEL_INCLUDES` into
|
|
|
+ :command:`try_compile` calls that use the
|
|
|
+ :ref:`whole-project signature <Try Compiling Whole Projects>`.
|
|
|
+ This is primarily intended as a way for dependency providers to be enabled
|
|
|
+ in such :command:`try_compile` calls.
|
|
|
+
|
|
|
+* A :prop_tgt:`VS_FILTER_PROPS` target property was added to tell
|
|
|
+ :ref:`Visual Studio Generators` to use a custom MSBuild filter
|
|
|
+ ``.props`` file.
|
|
|
+
|
|
|
+Modules
|
|
|
+-------
|
|
|
+
|
|
|
+* The :module:`ExternalProject` module's :command:`ExternalProject_Add`
|
|
|
+ command gained a ``TLS_VERSION <min>`` option, and support for the
|
|
|
+ :variable:`CMAKE_TLS_VERSION` variable and :envvar:`CMAKE_TLS_VERSION`
|
|
|
+ environment variable, to specify the minimum TLS version for connections
|
|
|
+ to ``https://`` URLs.
|
|
|
+
|
|
|
+* The :module:`FindBacktrace` module now provides an imported target.
|
|
|
+
|
|
|
+* The :module:`FindBLAS` and :module:`FindLAPACK` modules gained
|
|
|
+ support for ``libblastrampoline``.
|
|
|
+
|
|
|
+* The :module:`FindCUDAToolkit` module now provides a target for
|
|
|
+ ``libnvfatbin`` and ``libnvfatbin_static``, if found.
|
|
|
+
|
|
|
+* The :module:`FindCUDAToolkit` module now searches the
|
|
|
+ :variable:`CMAKE_CUDA_COMPILER <CMAKE_<LANG>_COMPILER>`
|
|
|
+ variable and the :envvar:`CUDACXX` environment variable
|
|
|
+ even when the ``CUDA`` language isn't enabled.
|
|
|
+
|
|
|
+* The :module:`FindOpenMP` module gained an ``OpenMP_RUNTIME_MSVC``
|
|
|
+ option to control the OpenMP runtime used with MSVC.
|
|
|
+
|
|
|
+* The :module:`FindPython` and :module:`FindPython3` modules gained
|
|
|
+ support for the free threaded Python version.
|
|
|
+
|
|
|
+* The :module:`FindPython`, :module:`FindPython2`, and :module:`FindPython3`
|
|
|
+ modules, on Windows, now offer better support for the Python debug variant:
|
|
|
+
|
|
|
+ * new variables:
|
|
|
+
|
|
|
+ * ``Python_EXECUTABLE_DEBUG``
|
|
|
+ * ``Python_INTERPRETER``
|
|
|
+ * ``Python_DEBUG_POSTFIX``
|
|
|
+
|
|
|
+ * new targets:
|
|
|
+
|
|
|
+ * ``Python::InterpreterDebug``
|
|
|
+ * ``Python::InterpreterMultiConfig``
|
|
|
+
|
|
|
+ The ``python_add_library()`` command now manages the
|
|
|
+ :prop_tgt:`DEBUG_POSTFIX` target property based on the value
|
|
|
+ of the ``Python_DEBUG_POSTFIX`` variable.
|
|
|
+
|
|
|
+Generator Expressions
|
|
|
+---------------------
|
|
|
+
|
|
|
+* The :genex:`<LANG>_COMPILER_FRONTEND_VARIANT <C_COMPILER_FRONTEND_VARIANT>`
|
|
|
+ family of generator expressions were added to access the value of the
|
|
|
+ associated :variable:`CMAKE_<LANG>_COMPILER_FRONTEND_VARIANT` variables.
|
|
|
+
|
|
|
+* Link features, as used with the :genex:`LINK_LIBRARY` generator expression,
|
|
|
+ gained the ability to have properties that describe their behavior by
|
|
|
+ specifying the :variable:`CMAKE_LINK_LIBRARY_<FEATURE>_PROPERTIES` or
|
|
|
+ :variable:`CMAKE_<LANG>_LINK_LIBRARY_<FEATURE>_PROPERTIES` variables.
|
|
|
+
|
|
|
+* The :genex:`QUOTE` generator expression was added to evaluate to ``"``.
|
|
|
+
|
|
|
+* The :genex:`TARGET_PROPERTY` generator expression learned to evaluate
|
|
|
+ :ref:`custom transitive properties <Custom Transitive Properties>`
|
|
|
+ defined by new :prop_tgt:`TRANSITIVE_COMPILE_PROPERTIES` and
|
|
|
+ :prop_tgt:`TRANSITIVE_LINK_PROPERTIES` target properties.
|
|
|
+
|
|
|
+* The :genex:`TARGET_PROPERTY` generator expression now evaluates target
|
|
|
+ properties :prop_tgt:`INTERFACE_LINK_OPTIONS`,
|
|
|
+ :prop_tgt:`INTERFACE_LINK_DIRECTORIES`, and
|
|
|
+ :prop_tgt:`INTERFACE_LINK_DEPENDS` correctly by following private
|
|
|
+ dependencies of static libraries. See policy :policy:`CMP0166`.
|
|
|
+
|
|
|
+CTest
|
|
|
+-----
|
|
|
+
|
|
|
+* The :command:`ctest_submit` command and :option:`ctest -T Submit <ctest -T>`
|
|
|
+ step gained ``TLSVersion`` and ``TLSVerify`` options to control negotiation
|
|
|
+ with ``https://`` URLs. See the :variable:`CTEST_TLS_VERSION` and
|
|
|
+ :variable:`CTEST_TLS_VERIFY` variables.
|
|
|
+
|
|
|
+CPack
|
|
|
+-----
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack Inno Setup Generator` is now available
|
|
|
+ on non-Windows hosts.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack NuGet Generator` can now generate dependency groups
|
|
|
+ for framework-specific dependencies. The :variable:`CPACK_NUGET_PACKAGE_TFMS`
|
|
|
+ variable was added to specify a list of target framework monikers (TFMs)
|
|
|
+ for which groups should be generated.
|
|
|
+
|
|
|
+* The :cpack_gen:`CPack WIX Generator` gained support for WiX Toolset v4.
|
|
|
+ See the :variable:`CPACK_WIX_VERSION` variable.
|
|
|
+
|
|
|
+Deprecated and Removed Features
|
|
|
+===============================
|
|
|
+
|
|
|
+* The :module:`FindBoost` module has been removed by policy :policy:`CMP0167`.
|
|
|
+ Port projects to upstream Boost's ``BoostConfig.cmake`` package
|
|
|
+ configuration file, for which ``find_package(Boost)`` now searches.
|
|
|
+
|
|
|
+* Calling :command:`FetchContent_Populate` with just the name of a
|
|
|
+ dependency is now deprecated. Projects should call
|
|
|
+ :command:`FetchContent_MakeAvailable` instead. See policy :policy:`CMP0169`.
|
|
|
+ Calling :command:`FetchContent_Populate` with full population details
|
|
|
+ rather than just a dependency name remains fully supported.
|
|
|
+
|
|
|
+* The :generator:`Visual Studio 9 2008` generator has been removed.
|
|
|
+
|
|
|
+Other Changes
|
|
|
+=============
|
|
|
+
|
|
|
+* The precompiled Windows ``.msi`` installers provided on
|
|
|
+ `cmake.org <https://cmake.org/download/>`_, when performing a fresh
|
|
|
+ installation, now modify the system-wide ``PATH`` by default.
|
|
|
+ When replacing an existing installation of 3.30 or later, the ``PATH``
|
|
|
+ modification preference is preserved by default.
|
|
|
+
|
|
|
+* The official ``.zip`` source archive provided on
|
|
|
+ `cmake.org <https://cmake.org/download/>`_ now uses LF newlines,
|
|
|
+ instead of CRLF newlines, for consistency with modern conventions.
|
|
|
+
|
|
|
+* The durations printed after "Configuring done" and "Generating done"
|
|
|
+ messages now reflect time spent in generator-specific steps, and
|
|
|
+ in a code model evaluation step at the beginning of generation that
|
|
|
+ was not previously captured. Printed durations may appear longer
|
|
|
+ than in previous versions of CMake, but are more accurate.
|
|
|
+
|
|
|
+* :module:`FetchContent` now prefers to populate content directly rather
|
|
|
+ than using a separate sub-build. This may significantly improve configure
|
|
|
+ times on some systems (Windows especially, but also on macOS when using
|
|
|
+ the Xcode generator). Policy :policy:`CMP0168` provides backward
|
|
|
+ compatibility for those projects that still rely on using a sub-build for
|
|
|
+ content population.
|
|
|
+
|
|
|
+* When :variable:`FETCHCONTENT_FULLY_DISCONNECTED` is set to true,
|
|
|
+ :command:`FetchContent_MakeAvailable` and the single-argument form of
|
|
|
+ :command:`FetchContent_Populate` require that the dependency's source
|
|
|
+ directory has already been populated. CMake 3.29 and earlier did not
|
|
|
+ check this requirement, but it is now enforced, subject to policy
|
|
|
+ :policy:`CMP0170`.
