clang-cl doesn't recoganise command line option "-fcoroutines-ts"

[missdeer]

As titled. But it works like MSVC, leaving blank is OK. Maybe something like below:

macro(qcoro_enable_coroutines)
    if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU")
        set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fcoroutines")
    elseif (CMAKE_CXX_COMPILER_ID STREQUAL "AppleClang")
        set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fcoroutines-ts")
    elseif (CMAKE_CXX_COMPILER_ID STREQUAL "Clang")
        if (MSVC)
            # Clang-cl works like MSVC that auto-enables coroutine support when C++20 is enabled
        else()
            set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fcoroutines-ts")
        endif()
    elseif (CMAKE_CXX_COMPILER_ID STREQUAL "MSVC")
        # MSVC auto-enables coroutine support when C++20 is enabled
    else()
        message(FATAL_ERROR "Compiler ${CMAKE_CXX_COMPILER_ID} is not currently supported.")
    endif()
endmacro()
