It looks like this is introducing a hard dependency on Python.  (We use python for a lot of things, but nothing actually required to build the compiler, as far as I know.)

That's not necessarily a problem, I guess, but we'd want to update the system requirements, and fix CMake to give a god error message if it's missing.
