Please give use a more complete example, with the #include.

The documentation of Polyhedral_mesh_domain_with_features_3 is not correct, 
in my opinion. Its constructor documentation refers to a type "Polyhedron" 
without telling anything about it. Actually, that class template has a second 
template parameter; try that:

typedef CGAL::Polyhedral_mesh_domain_with_features_3<IGT, Polyhedron> 
Mesh_domain;
