AFAIK, yes, if you can write a single process that spawns and waits on 
your other processes. (If you're relying on something like python or a 
UNIX shell being available, you could leverage that, with a script, as 
the controller process.)

Basically, anything you can coerce into 'run a single process with some 
arguments, wait on it to exit, and take the exit status and/or output 
parsing as the test result' can be a CTest test.
