Could you please open an issue about the copy_face_graph problem, with
a minimal example we can try compile?

https://github.com/CGAL/cgal/issues

Also note that the API for region growing code for polygon meshes was
kind of broken and it has been fixed in CGAL 5.6. So now you should be
able to use the default Polyhedron directly in your code.

Best,

Sebastien.
