Hi,

The error below is a link error due to the taucs_ccs_free() function missing. You should 
link with TAUCS.

Finding the proper libraries to link with TAUCS is tedious, thus I recommend you to cut 
and paste the code related to TAUCS in 
CGAL-3.4/examples/Surface_mesh_parameterization/CMakeLists.txt (assuming that you use CMake).

Best regards,
