This library is built from the a version of SuiteSparse's CSparse
library.  More precisely, the file extlibs/csparse/csparse.c in
sofa-framework is a like a concatenation of the files CSparse/Source/*.c
in the suitesparse package.

I tried to build sofa-framework against libsuitesparse-dev using the
simple patch attached below.  However, the compilation fials.  I did not
investigate this issuedeeply, but it seems that extlibs/csparse/csparse.c
contains an old version of SuiteSparse's CSparse.

I see the following solutions for this:

1) Ask the upstream authors to link agaisnt SuiteSparse instead of
   shipping a copy of the CSparse library and adapt their code for working
   with a modern version of the library.
   
2) Link against an internal version of CSparse but put it somewhere else
   (e.g. /usr/lib/sofa/libcsparse*).  I do not now if this is fully
   appropriate for the libcsparse.so symlink included in libsofa1-dev.

Cheers,
