Major Description
Currently, if you do a clean CMake configuration and build, and the only thing you build is libprocess-tests, it fails to find gmock and gtest. This is because while libprocess-tests depends on them, it is only stout-tests that builds.
If you first build stout-tests, and then libprocess-tests, the dependencies will be built. But this is incorrect.
I'll fix it in my CMake refactor.
