Thinking about it, it could be tricky since spglib handles the python 
build from cmake with no setup.py.  The others run the two parts 
separately, cmake for the library and python setup for the python 
module.  Seems to be a flaw in cmake that it can't handle multiple 
pythons. Could possibly run cmake multiple times specifying the python 
version for each run.

True.  For now I'll configure the client packages to run their tests 
only on default python then.
