CGAL-3.5 has been tested with gcc-4.4. The problem must be elsewhere. Can you 
give us the full error log?

Actually, the CMake macro FindTAUCS, called by find_package(TAUCS), handles 
the dependencies of TAUCS.

You are right. But sometimes it is quite difficult to describe: that depends 
on the platform. Anyway, I agree such things should be documented, as much as 
possible.

Yes, that will be done.
