Laurent Rineau 8e167590c8 Use include_directories(SYSTEM ...) for 3rd-party libraries
gcc has an option -isystem, that can replace -I. The documentation is:

 -isystem dir

     Search dir for header files, after all directories specified by -I but
     before the standard system directories. Mark it as a system directory,
     so that it gets the same special treatment as is applied to the
     standard system directories. If dir begins with "=", then the "=" will
     be replaced by the sysroot prefix; see --sysroot and -isysroot.


The "special treatment" means that gcc will not warn about constructions in
headers in directories pointed by -isystem instead of -I.

In the CGAL testsuite, there are a lot of warnings that comes from
third-party libraries (mostly from Boost, but also from Eigen).

This patch tells cmake to use -isystem with gcc, for all CGAL 3rd-party
directories.
