[CMake] make didn't compile

[Enrique Izaguirre]

Hello friends,

As far as I have been investigating this problem, seems that GNU compilers
have a problem when combining -c flag with multiple files and -o flag to
generate an executable.

The problem is that CMake somehow is generating the compile command, and
assembling it wrongly. Is there any way to overcome this issue?

Thanks

Best Regards

Enrique
