[CMake] Test Script problems on Windows

[Allen D Byrne]

Well it turns out the problem was in the execute_process script. I had the :
       OUTPUT_FILE ${TEST_OUTPUT}
    ERROR_FILE ${TEST_OUTPUT}

both going to one file - Windows couldn't handle that. Changing that allowed the command to actually execute,    

NOW, I have to deal with the CRLF issue in the stdout file. The reference file only has LF line endings.
