No. (Actually, it *might* be possible, but I wouldn't classify it as trivial
or easy, especially with any significant number of ExternalProject calls.
You'd have to add all the ExternalProject generated stamp files to the list
of extra clean files at the top level...)

But a very easy equivalent is simply blow away your whole build tree, re-run
cmake, and then make again.

Especially for a SuperBuild style project, wherein everything that you are
building is an ExternalProject, the top level configure with CMake is very
quick.
