Probably the most important thing that has to be done, is that the section of
vtkWrapPython.cmake that starts with if(VTK_WRAP_PYTHON_FIND_LIBS)
should be moved to FindPythonLibs.cmake.  Ideally it should be done
in such a way that that the changes could eventually go into CMake itself
(i.e. variables should be renamed so that they don't contain VTK, etc.)
I'm sure that VTK isn't the only project that needs to find the python debug
libs.
