If you're doing it due to dependencies, there is the DEPENDS argument to 
ExternalProject_Add to declare dependencies, which will force build order.

(Or, as Sören noted, you can just turn off parallel building altogether.)

You could also artificially make each external project depend on the 
last one to force them to build serially without having to globally 
disable parallel building.
