There are a lot of things that do not compile in the example you has provided:

Missing #include <CGAL/Exact_predicates_inexact_constructions_kernel.h>

I do not have a definition for that type template CgalPolyhedron. But anyway 
it is not used in the following so I commented the line.

CGAL::Mesh_criteria_3 is a class template. It cannot be used like that. You 
need to specify template arguments. Actually the type "Tr".


Anyway, I found out one problem in your use of 
Polyhedral_mesh_domain_with_features_3. If you write:

  CGAL::Polyhedral_mesh_domain_with_features_3<IGT, Polyhedron>

then the Polyhedron traits class must also be IGT, and not K.
