[strongSwan-dev] Can a plugin use another plugin?.

This is possible, but you should avoid relying on hard-coded symbol
names from a different plugin. Instead, you may use the lib->set()/get()
functions to export a symbol using a well-known name, and import it from
another plugin. You can also introduce CUSTOM plugin dependencies to
make sure these dependencies are satisfied.

The eap-aka plugin for example uses this to export the "aka-manager" ,
which is then used by the eap-aka-3gpp2 plugin to provide the backend
through [2].
