What do you mean by "conform to the input PLC"? The tetrahedral mesh 
generator 
in CGAL can remesh a polyhedron and respect its sharp edges (that is new in 
CGAL-3.8).

As for the density, you can create a special model of the concept 
MeshCriteria_3. For a client of GeometryFactory, I have writen such a 
criteria 
class that reads the sizing field from a 3D scalar image, and ensure that for 
each tetrahedron in the meshing domain, its size is smaller than the value in 
the image at the center of the tetrahedron.
