You could try setting RUNPATH/RPATH into the extension module.  If
it's using distutils you can use --rpath to setup.py build_ext, see
the --help of the build_ext sub-command.

I forgot to say but I also tried with the rpath but library load of
Python does not seems to follow it.

Since I am also the packager of Scilab, I could also move the library
into /usr/lib but since Scilab has many libraries, I was hoping to store
them separately but if there is no other way, I could do that...

Or you could just try building libraries in /usr/lib/scilab with rpath. Then cdll.LoadLibrary("/usr/lib/scilab/libscilab.so") should work as intended.
