build: Overlay package isn't used by a dependent package if the dependent package has already been configured against system package

[jbohren]

Observed:

If I run catkin build once with a package which depends on a package installed to the system (or an underlay workspace), and then add a source checkout of that package to my workspace, the dependent package is still configured against the system/underlay package, and not the source checkout in the same workspace.

Fix:

Force a re-configuration of packages which depend on packages which were added to this workspace since the last build.

Just for the record: reinvoking CMake is not sufficient in this case. You must remove the CMake cache which means basically wipe the build folder.

Right, and the catkin build verb should be able to do that in the context of an isolated build. Thanks for the clarification.

This is related to #257.
