If you don't need to worry about cross-platform compilation & support (and
sounds like you don't), the most straight-forwarded way to do this is to
deploy your dll to a Maven repository with type "dll", declare a straight-up
dependency to it in your pom and then use the dependency plugin to copy the
lib to the target dir or other suitable location for development environment
and structure you assembly (or whatever is the format of the actual
delivery) similarly. If cross-platform support is desired, nar plugin (
http://java.freehep.org/freehep-nar-plugin/intro.html) is a bit more
involving but simplifies things greatly. However, using it requires some
code changes.
