John is right. The external project may be at the bottom of a chain of (my own) project dependencies. I need to preserve the ability to easily rebuild just my projects (and their dependencies), not external projects. Think of ExternalProject as a replacement for pre-built libraries, and you'll see where I'm coming from.
Perhaps I need to file a feature request on Mantis.
