ENH: Generator - Added CMakeLists.txt allowing to compile PythonQtGenerator in a cross-platform fashion

Note it's possible to run the generator from either the build directory or
the install directory.

Indeed, the dependent files (typesystem_*.xml, build_*.xml,
qtscript_masterinclude.h and parser/rpp/pp-qt-configuration)
have the appropriate install rules and are also copied to the build directory.
