Found it myself. For completeness and documentation purposes: Add a
custom target which removes the *-complete (see ExternalProject.cmake on
where it is located, it is a bit tricky) and -*configure stamps. Of
course, it should always run and depend on the external project target.

The thing I'm struggling with now is installing the various sub-projects
into the system. Seems like it is impossible to install an imported
target [1], but guessing and hard coding the paths is also not very
attractive, but probably the only way to go at the moment. If anybody
has a better idea, please speak up...
