Craig, My cmake-based build system in my company's CI framework works exactly that way: there's a generic cmake script[1] (invoked with cmake -P) that reads in a file which contains repo-urls and build parameters for 50+ projects and builds them for 3 platforms (linux, win, mac) 5 compilers (cross-compilers, too) invoking child cmake builds with execute_process. This is done after each push and one daily clean build.
I've never had any problems with that approach. On the other hand, the system was originally designed with ExternalProject and I had many problems.
