[CMake] compiling for both python2 and python3

[Petr Kmoch]

Hi Alexander.

No time for a full answer now, but a hint: it's possible to
add_subdirectory() the same CMakeLists.txt multiple times, if you use a
different binary dir each time. You can set some variables in the parent
CMakeList and use them in the child one to generate slightly different
projects from the same source.
