# This CMake toolchain file configures a CMake, non-'Visual Studio Generator' build to use
# the Clang compilers and tools on Windows.
#
# The following variables can be used to configure the behavior of this toolchain file:
#
# | CMake Variable | Description |
# |---------------------------------------------|-----------------------------------------------------------------------------------------------------------------|
# | CMAKE_SYSTEM_VERSION | The version of the operating system for which CMake is to build. Defaults to '10.0.19041.0'. |
# | CMAKE_SYSTEM_PROCESSOR | The processor to compiler for. One of 'X86', 'AMD64', 'ARM', 'ARM64'. Defaults to ${CMAKE_HOST_SYSTEM_PROCESSOR}. |
# | CMAKE_WINDOWS_KITS_10_DIR | The location of the root of the Windows Kits 10 directory. |
# | CLANG_TIDY_CHECKS | List of rules clang-tidy should check. Defaults not set. |
# | TOOLCHAIN_UPDATE_PROGRAM_PATH | Whether the toolchain should update CMAKE_PROGRAM_PATH. Defaults to 'ON'. |
# | TOOLCHAIN_ADD_VS_NINJA_PATH | Whether the toolchain should add the path to the VS Ninja to the CMAKE_SYSTEM_PROGRAM_PATH. Defaults to 'ON'. |
#
# The toolchain file will set the following variables:
#
# | CMake Variable | Description |
# |---------------------------------------------|-------------------------------------------------------------------------------------------------------|
# | CMAKE_C_COMPILER | The path to the C compiler to use. |
# | CMAKE_CXX_COMPILER | The path to the C++ compiler to use. |
# | CMAKE_MT | The path to the 'mt.exe' tool to use. |
# | CMAKE_RC_COMPILER | The path tp the 'rc.exe' tool to use. |
# | CMAKE_SYSTEM_NAME | "Windows", when cross-compiling |
# | WIN32 | 1 |
# | CMAKE_CXX_CLANG_TIDY | The commandline clang-tidy is used if CLANG_TIDY_CHECKS was set. |
