The whole python support IMHO should be rewritten as mentioned here:
http://vtk.org/Bug/bug.php?op=show&bugid=2257
As for the installation thing, it would be nice if the CMake Modules had
an interface (?mymodule_INSTALL_PREFIX ?) to specify default
installation path. I am thinking that this should be the same issue for
Tcl, Python, Java.
2 cents,
Mathieu
