Nope... my users don't want to do that... (or rather I don't know which 
DESTDIR, if any, they'll use at all, so the solution cannot involve 
anything like it)

They want to install CGAL in the "correct" place, whatever that is, but 
without FindCGAL.cmake unless explictely indicated.

Of course I can use an option variable at configuration time, but I was 
thinking on something less intrusive.
