Hi,

just to let you know, I had the same requirement as well as compiler errors.

Having looked at the CGAL code it seems that the Mesh_facet_criteria_3 
template is missing a constructor overload which could take a variable 
sizing field for the facet distance (CGAL version 3.9). As you said this 
is in contrast to the documentation for the "facet_distance" criteria 
here 
http://www.cgal.org/Manual/3.9/doc_html/cgal_manual/Mesh_3/Chapter_main.html#Section_50.2
