Error in setting compiler options

[william-swy]

From my understanding MINGW takes GCC flags.

So in this conditional

if(MSVC OR MSYS OR MINGW)
    set(COMPILER_OPTIONS ${COMPILER_OPTIONS} /Ox /DAE_OS=AE_WINDOWS)
    execute_process( COMMAND wmic CPU get Name OUTPUT_VARIABLE CPU_NAME)
    if (${CPU_NAME} MATCHES "Intel")
        set(COMPILER_OPTIONS ${COMPILER_OPTIONS} /DAE_CPU=AE_INTEL)
    endif()

elseif(UNIX)
    set(COMPILER_OPTIONS ${COMPILER_OPTIONS} -O3 -DAE_OS=AE_POSIX -pthread)
    execute_process( COMMAND uname -m OUTPUT_VARIABLE ARCHITECTURE)

    if (${ARCHITECTURE} MATCHES "x86_64")
        set(COMPILER_OPTIONS ${COMPILER_OPTIONS} -DAE_CPU=AE_INTEL)
    endif()
endif()

I'm quite sure MINGW option should be moved with the UNIX branch. I have MINGW on my windows computer and the current compiler options makes g++.exe generate errors where it interprets /Ox as a path. When I add MINGW to the UNIX conditional, I get no errors.
