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.

| Clean the CMake configuration:
|
| - CGALConfig_install.cmake.source.in is removed. The variable
| SOURCE_INSTALL/CGAL_SOURCE_INSTALL were unused, and probably not tested
| for a long time (I found errors in
| CGALConfig_install.cmake.source.in). This has been cleaned.
|
| - CGALConfig_install.cmake.fhs.in is renamed (no .fhs. in it).
|
| - The module path is now modified in a macro (defined in
| CGAL_Macros.cmake), and the variable CGAL_CMAKE_MODULE_PATH is no
| longer stored or used in CGALConfig.cmake (the reason is that is was
| used as a path, where it is actually a list of paths).
|
| - The UseCGAL.cmake file only link with CGAL libraries that has been
| configured.
