I made some searches (here, in google and in WiKi) and nothing came out so far.

One of the possibilities would be to build a project from scratch using just the main program. The project will pick up all directly referenced programs or libraries.

You may also try FoxLint from http://leafe.com/dls/vfp though it's not exactly what you're looking for.
