This update for cmake3 fixes the following issues:

- Needed for Firefox 128 (bsc#1226316)
  (Dependency chain: cmake3 -> Rust1.78 -> Firefox)
  
- Update to 3.20.0

  * The “cmake_path()” command was added for operations on
    filesystem paths.
  * The “target_sources()” command now supports targets created
    by the “add_custom_target()” command.
  * The “ExternalProject” module “ExternalProject_Add()” function
    gained a “CONFIGURE_HANDLED_BY_BUILD” option.
  * “ctest(1)” gained a “–test-dir” option to specify the directory
    in which to look for tests.

- update to 3.19.7:

  * With :ref:`Visual Studio Generators` for VS 2017 and higher, the
    :variable:`CMAKE_GENERATOR_TOOLSET` field ``version=`` now accepts
    three-component MSVC toolset versions such as ``14.28.29910``.
    See the :variable:`CMAKE_VS_PLATFORM_TOOLSET_VERSION` variable.

- cmake 3.19.6:

  * The cmake-presets(7) feature no longer allows comments in
    CMakePresets.json or CMakeUserPresets.json files. This was
    mistakenly allowed by the implementation in 3.19.0 to 3.19.5

- Update to CMake 3.19.5

  * FindBoost: Add support for Boost 1.75
  * FindCUDAToolkit: Restore use of CUDA_PATH environment variable

- cmake 3.19.4:

  * fixes for other platforms

- cmake 3.19.3:

  * FetchContent: Relative SOURCE_DIR override cannot be a hard error
  * FindMPI: remove single quotes from include path
  * FindHDF5: Fix finding both debug and release libs
  * cmake-gui: Restore linking of Qt resources
  *  cmMakefile: Don't expand bracket arguments in --trace-expand

- update to 3.19.2:

  * various Apple-Silicon support fixes
  * The CMAKE_ISPC_HEADER_SUFFIX variable and corresponding ISPC_HEADER_SUFFIX
  target property were added to control the header suffix used by ISPC
  compiler generated headers.

- cmake 3.19.1:

  * avoid breaking projects relying on using the LANGUAGE property
    to cause the specified language's compiler to be used
  * CUDA 11.1 support for Clang.

- cmake 3.19.0:

  * cmake(1) and cmake-gui(1) now recognize CMakePresets.json and
    CMakeUserPresets.json files
  * support for ISPC
  * exctend CUDA language support for Clang
  * extend cmake-file-ap "codemodel"
  * cli --install supports --default-directory-permissions
  * cli supports creating hardlinks
  * CMake GUI now has an environment variable editor
  * Multiple cmake commands support new options and subcommands
  * Multiple variables added or functionalities extended
  * Multiple new modules and added functionality to existing modules
  * Compatibility with versions of CMake older than 2.8.12 is now
    deprecated and will be removed from a future version. Calls to
    cmake_minimum_required() or cmake_policy() that set the policy
    version to an older value now issue a deprecation diagnostic.
  * cmake-gui now requires Qt5

- cmake 3.18.4:

  * no upstream changelog

- update to 3.18.3:

  * The Compile Features functionality was updated for MSVC 19.28

- reapply this change (bsc#1174581):
  * Fix setting CMAKE_INSTALL_LIBDIR in cmake macro
  * This is a relative path, see `cmake --help-module GNUInstallDirs`

- update to 3.18.2:

  * The default value of :variable:`CMAKE_AUTOMOC_PATH_PREFIX` was changed to
  ``OFF`` because this feature can break existing projects that have
  identically named header files in different include directories.
  This restores compatibility with behavior of CMake 3.15 and below.
  * The :manual:`Compile Features <cmake-compile-features(7)>` functionality
  was updated for MSVC 19.27 as mentioned above.

- cmake 3.18.1:
  * Revert undocumented fix in 3.18.0 in the add_test() command
    for special characters to avoid breaking existing projects that
    worked around the issue. Will be reintroduced later

- update to cmake 3.18.0

  * The “CUDA” language can now be compiled using Clang on non-Windows platforms.
  * “cmake(1)” gained support for profiling of CMake scripts
  * The “cmake_language()” command was added for meta-operations on
    scripted or built-in commands, starting with a mode to “CALL” other
    commands, and “EVAL CODE” to inplace evaluate a CMake script.
  * The “find_program()”, “find_library()”, “find_path()” and
    “find_file()” commands gained a new “REQUIRED” option that will stop
    processing with an error message if nothing is found.
  * The “CheckLinkerFlag” module has been added to provide a facility to
    check validity of link flags.
  * “ccmake(1)” learned to read a “CCMAKE_COLORS” environment variable
    to customize colors.

- DCMAKE_MODULES_INSTALL_DIR should be %{_libdir}/cmake/%{name}
- Set CMAKE_INSTALL_LIBEXECDIR=%{_libexecdir}
- Use -DCMAKE_SKIP_INSTALL_RPATHS:BOOL=ON instead of completely
  removing rpaths. bsc#1172331

- cmake 3.17.3:

  * Selection of the Objective C or C++ compiler now considers the
    CC or CXX environment variable if the OBJC or OBJCXX
    environment variable is not set
  * The FindPkgConfig module now extracts include directories
    prefixed with -isystem into the *_INCLUDE_DIRS variables and
    INTERFACE_INCLUDE_DIRECTORIES target properties
  * FindOpenSSL: Detect OpenSSL 3.0.0 (bsc#1172267)

- cmake 3.17.2:

  * fixes dealing with boost 1.73

- cmake 3.17.1:

  * The :cpack_gen:`CPack NSIS Generator` now requires NSIS 3.0 or later
