I have difficulties to install the debian package of kamailio I have build from source

Creation works fine. (make cfg, configuration of proper debian in pkg/debian/deb , make deb)

But kamailio tries to find module here : /usr/lib/x86_64-linux-gnu/kamailio/modules/

and modules are installed in /usr/lib64/

Of course, it works fine by specifying -L with actual path.

I have tried also to download the source of debian package with same result.

I have missed some steps.
