[CMake] Subset testing with CTest

[David Cole]

Similar to running 'make' in a sub-directory to build just that
directory and below... running 'ctest' in a sub-directory will just
run the tests for that directory.

Are you asking to be able just to run the tests, or to submit just
those tests to a dashboard?

Just running them is already possible. Sending them to a dashboard,
you'd have to use the -R matching technique...
