Laurent R.: You are right, this may be related to f2c.

On my Linux box, cmake prints
...
-- LAPACK include:
-- LAPACK definitions: -DLAPACK_USE_F2C
-- LAPACK libraries: 
/proj/geometrica/home/TAUCS/external/lib/linux/liblapack.a;/proj/geometrica/home/TAUCS/external/lib/linux/libg2c.so
-- LAPACK link flags:
-- BLAS include:
-- BLAS definitions: -DBLAS_USE_F2C
-- BLAS libraries: 
/proj/geometrica/home/TAUCS/external/lib/linux/libcblas.a;/proj/geometrica/home/TAUCS/external/lib/linux/libf77blas.a;/proj/geometrica/home/TAUCS/external/lib/linux/libatlas.a;/proj/geometrica/home/TAUCS/external/lib/linux/libg2c.so
-- BLAS link flags:
...

Martial:
Please run cmake-gui in Polyhedron/demo/Polyhedron/ folder and set the next 
variables:
BLAS_DEFINITIONS=-DBLAS_USE_F2C
BLAS_LIBRARIES=/usr/local/lib/libcblas.a;/usr/local/lib/libf77blas.a;/usr/local/lib/libatlas.a;/usr/local/lib/libg2c.so
LAPACK_DEFINITIONS=-DLAPACK_USE_F2C
LAPACK_LIBRARIES=/usr/local/lib/liblapack.a;/usr/local/lib/libg2c.so
