You can use EXECUTE_PROCESS and python distutils to obtain python
attributes.  See
http://plplot.svn.sourceforge.net/viewvc/plplot/trunk/cmake/modules/python.cmake
for an example of this approach for determining the installation directory.
(Note, we don't bother to obtain the explicit python version, but it would
certainly be possible to do that with this general approach.) You may also
like to look in trunk/bindings/python and trunk/bindings/swig-support to see
how we build a python interface to the PLplot core C library. Finally,
trunk/examples/python also has lots of plotting examples done with our
python interface to PLplot.
