I agree the error message is not verbose.

You are probably missing Eigen and/or you haven't defined 
CGAL_EIGEN3_ENABLED as documented here:

http://doc.cgal.org/latest/Surface_modeling/classCGAL_1_1Surface__mesh__deformation.html

if you want to use the default template parameters.
If you look at the cmakelists.txt coming with the examples you'll
see that it is done there.

Sebastien.
