No. The CGAL 2D mesh generator¹ needs a bounded domain to work on. The 
boundary of the domain must be given as constraints in a constrained Delaunay 
triangulation. However, at the end of the meshing process, the constrained 
Delaunay triangulation is guaranteed to be a conforming Delaunay 
triangulation. In other words the constrained Delaunay triangulation is equal 
to the Delaunay triangulation of its vertices. Maybe it is sufficient for 
your 
needs.
