Hi Scott,

It makes no sense to stipple together a g++ -L ....

The CGAL library, as well as the examples and demo come
with CMakeLists.txt  files for cmake, you have to configure
and generate a Makefile  (or whatever generator you choose)
and then call make, and then you have your demo.

Note also that what I write here informally,
is documented.

Best,

Andreas
