CGAL 6.x still unconditionally includes boost/config.hpp in its
config.h, so Boost headers are required even with CGAL_DISABLE_GMP/MPFR.
Use system Boost via find_package instead of the removed 211 MB tarball.
Tests-only mode remains completely dependency-free.
Install: brew install boost (macOS)
apt install libboost-dev (Debian/Ubuntu)
