I could reproduce this. It occurs when building CGAL 3.8. It is not a compiler 
error, instead it is an error of Qt generating the moc-file (the "moc" program 
of Qt). For some reason, boost is included in this file where moc is run. As you
see the last step is

[ 29%] Generating __/__/include/CGAL/Qt/moc_GraphicsItem.cxx

which is not a compiler step.

I suppose that this either needs a fix in CGAL, or in Qt in the moc generator. 
However, I don't know a quick fix for this...
