CGAL users discussion list

Looking at the macport repo, it looks like the maintainer have
disabled CGAL_Qt5:

"bump to 4.7 and move to github port. Qt5 disabled because I can’t build 
it on my computer. To be enabled later."

https://trac.macports.org/browser/trunk/dports/gis/cgal/Portfile

You should probably build CGAL yourself (even if looking at the script
adding +qt5 should do the job, but I don't know anything about port
scripts).
