But the GPL says that if you link two pieces of software together and

under terms that are compatible with the GPL.

I'm not sure what you mean by "module".  The GPL doesn't make a
distinction between a "module" or a "plugin".  If you want the
interpretation of the FSF, check the section of the GPL FAQ concerning
plugins on the gnu.org web pages.

The GPL applies if you create a derivative work.  If the communication
is through files, pipes, sockets, etc., and the code licensed under
GPL-incompatible terms is running in a separate process, then there
the GPL doesn't apply (again, see the GPL FAQ).
