[cmake-developers] [CMake] Path to vc_redist

[Roman Wüger]

Thank you Robert,

I came up with the following, maybe someone has a better idea:

if (WIN32)
    if(CMAKE_SIZEOF_VOID_P EQUAL 8) # 64-bit
        set(REDIST_ARCH x64)
    else()
        set(REDIST_ARCH x86)
    endif()
 
    set(REDIST_FILE vcredist_${REDIST_ARCH}.exe)
 
    set(CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS_SKIP TRUE)
    include(InstallRequiredSystemLibraries)
 
    # Check if the list contains minimum one element, to get the path from
    list(LENGTHCMAKE_INSTALL_SYSTEM_RUNTIME_LIBS libsCount)
    if (libsCount GREATER 0)
        list(GET CMAKE_INSTALL_SYSTEM_RUNTIME_LIBS 0 _path)
 
        get_filename_component(_path ${_path} DIRECTORY)
        get_filename_component(_path ${_path}/../../ ABSOLUTE)
 
        if (EXISTS "${_path}/${REDIST_FILE}") # VS 2017
            set(REDIST_FILE ${_path}/${REDIST_FILE})
        else()
            get_filename_component(_path ${_path}/1033ABSOLUTE)
            set(REDIST_FILE ${_path}/${REDIST_FILE})
        endif()
 
        install(PROGRAMS ${_path}/${REDIST_FILE})
    endif()
endif()
 
Regards
Roman
