[CMake] CMake Python support

[Marcel Loose]

Ah thanks,

I didn't know that byte code is incompatible between Python releases.
That's definitely a pitfall ;-). I agree that, in that case, it's better
to let the installer handle byte compilation. So, in short, I can do
with the existing FindPython* scripts, I guess?

Thanks for your prompt reply.

Best regards,
Marcel Loose.
