- If your system already has an outdated binary CGAL package installed (such as libcgal-dev) you best remove it with something like 'apt-get purge libcgal-dev'.
- If you custom-compiled BOOST, set the BOOST_ROOT environment variable to the installation location
- Download CGAL from  . Try to get the latest version.
sudo apt-get install libboost-dev cmake libmpfr-dev libgmp3-dev
tar -xf CGAL-*tar*
cmake . -DCMAKE_INSTALL_PREFIX=$HOME/openscad_deps
sudo make install
- Note that some older systems, like NetBSD5, wont compile CGAL - either because CGAL wasn't ported to work with them or their compiler is too old or other reasons.
