If you have a non-manifold polyhedron in an off-file,
you can try using CGAL::OFF_to_nef_3
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Nef_3_ref/Function_OFF_to_nef_3.html

like that:

#include <CGAL/OFF_to_nef_3.h>

........

std::ifstream ifile("myfile.off");
Nef_polyhedron N;
CGAL::OFF_to_nef_3(ifile,N);
