We do this commonly and use "make -j" to build multiple external
projects in parallel subject to their dependencies.  The DEPENDS
option should say "bring the dependency completely up to date
before starting to build the dependent".

Can you post an example CMakeLists.txt, along with the cmake and
make command lines you use to build it?

Thanks,
