The error says that linker can not find the CGAL library,
more precisely file with libCGAL basename.
Linker searches for this file in paths given with -L options,
so check if there is any file starting with libCGAL in following
directories (copied from your output above): /usr/lib

May be CGAL was installed into /usr/local prefix so the libraries can be
found in /usr/local/lib
