I have to agree here -- I don't think this will provide a significant speedup since building the library is really fast, and we're trying to move towards less and less complexity in our CMake. Hence I'm not sure this change is worth it.

Caching the tests would provide a huge speedup but as @philnik777 mentioned, it's a really scary thing to do and defeats one of the primary goals we have in the test suite, which is to test-as-we-ship.
