The move to Utilities is easy enough to do.

The find_package(PythonLibs) might be tricker than you suppose, though.
Right now VTK finds the python libs via some code in vtkWrapPython.cmake,
in the section that starts with  if(VTK_WRAP_PYTHON_FIND_LIBS), rather
than by calling find_package(PythonLibs) directly.  I don't know who put that
code in vtkWrapPython.cmake, it definitely does not belong there.
