yes, the QGLViewer packaging in Debian is quite strange.

Alejandro, I used the following flags when invoking cmake:

-DQGLVIEWER_INCLUDE_DIR=$HOME/local/include
-DQGLVIEWER_LIBRARY_RELEASE=/usr/lib/libqglviewer-qt4.so
-DQGLVIEWER_LIBRARY_DEBUG=/usr/lib/libqglviewer-qt4.so
-DCGAL_EXE_LINKER_FLAGS=-lCGAL_Qt4

The first one is equivalent to what Laurent already told you, but you
don't need to manually edit the CMakeCache.txt file. The next two are
required because the QGLViewer library name is non-standard in the
Debian package. The last flag is finally needed because there seems to
be a problem in the cmake setup of this demo.

Now all linker errors except one (undefined reference to "dgelss") are
gone. I don't have LAPACK/BLAS/TAUCS installed. Maybe this link error
does not show up if you have these libraries installed.
