[CMake] CMake Python support

[Marcel Loose]

Hi all,

Would it be worthwhile to add Python as a valid language to the
project() method? Or is it better to use the currently available
FindPython-like scripts.

My reason for asking is that oftentimes you'd like to byte-compile
Python source and install these byte-compiled files along with the
Python sources. If Python were a fully supported programming language,
then you could write the CMakeLists.txt files more or less the same way
as for other languages (e.g., like Java).

It's just a thought, and maybe I'm overlooking all kinds of potential
pitfalls. 

Best regards,
Marcel Loose.
