Use a base class to implement the common plugin API (generalization). The develop sub-classes that override the functions and variables of that API to provide the different plug-ins.

You may also want to look into MetaL which is a meta-programming compiler that has many modules that implement different compiler functionality as defined by bindings configuration in XML:
