How to enable C++17 in CMake

Question

I\'m using VS 15.3, which supports integrated CMake 3.8. How can I target C++17 without writing flags for each specific compilers? My current global settings don\'t work:

You can also use target_compile_options to set /std:c++latest flag for Visual Studio 2019

if (MSVC_VERSION GREATER_EQUAL "1900")
    include(CheckCXXCompilerFlag)
    CHECK_CXX_COMPILER_FLAG("/std:c++latest" _cpp_latest_flag_supported)
    if (_cpp_latest_flag_supported)
        target_compile_options(${TARGET_NAME} PRIVATE "/std:c++latest")
    endif()
endif()

Replace ${TARGET_NAME} with the actual target name.
