I think there is too much difference in GNU and MS compilers to be able
to just convert. I am sorry to say, but you probably need to dig in into
documentation for each compiler you want to support and do something like:

IF( "${CMAKE_C_COMPILER_ID}" STREQUAL "MSVC" )
  SET(CMAKE_CXX_FLAGS "MS compiler flags here")
ELSEIF ( "${CMAKE_C_COMPILER_ID}" STREQUAL "GNU" )
  SET(CMAKE_CXX_FLAGS "GNU compiler flags here")
ENDIF ()
