        check_c_compiler_flag(-Qspectre C__Qspectre_VALID)
        if(C__Qspectre_VALID)
                set(CMAKE_C_FLAGS "-Qspectre ${CMAKE_C_FLAGS}")
        endif(C__Qspectre_VALID)

and similar for C++.  (I'm not sure whether you can use / or whether CMake expects - to be used even with Windows 
programs, translating it to / as necessary.)
