Try that

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Regular_triangulation_3.h>
#include <CGAL/Regular_triangulation_euclidean_traits_3.h>
#include <CGAL/Triangulation_vertex_base_with_info_3.h>
#include <vector>

typedef CGAL::Exact_predicates_inexact_constructions_kernel            K;
typedef CGAL::Regular_triangulation_euclidean_traits_3<K> 
Traits;
typedef CGAL::Triangulation_vertex_base_with_info_3<unsigned, Traits>  Vb;
typedef 
CGAL::Triangulation_data_structure_3<Vb,CGAL::Regular_triangulation_cell_base_3<Traits> 
> Tds;
typedef CGAL::Regular_triangulation_3<Traits, Tds> RT3;
