Maybe it would have helped if you'd explain why you want to be able to
build your project on the other computer but don't want to deal with
building CGAL on that machine.

Not sure if cmake has a function for "give me the absolute path for the
current file". If not, the path has to be hard-coded somewhere ...

Can't you just use the same install location for CGAL on both machines?

If not, can't you adjust the absolute paths in CGALConfig.cmake (for
example with sed) automatically in some kind of "installer" for the
other machine?

Is CGAL the only problematic library? What about GMP, MPFR, etc.? Are
they at the same location on the other machine?
