Indeed.
I forgot to metion this as an alternative to removing .libs explicitely.
Sorry about that.

Notice that the first macro is global: turns off autolinking in ALL of CGAL, 
while the second is package-specific, taking the general form 
CGAL_NO_AUTOLINK_<PACKAGE>.

For the case ot TAUCS there is also CGAL_NO_AUTOLINK_LAPACK.
