The mesh produces by CGAL needs geometrical properties, mainly the Delaunay 
criterion. If the mesh you want to preserve does not have that property, the 
only hope is to remesh it using the CGAL 3D mesh generator, and then there 
will be hope that you can write a custom mesh domain class, that allows to 
mix 
you mesh with the levelset.

If you do that, the lines, corresponding to the edges of the input mesh, will 
be remeshed, and even then there is no guarantee that the facets of the input 
mesh can be represented by union of Delaunay facets.
