RunCMake already has tests of both types, so if we want to make
such a distinction then a lot more work is needed.

Using CMake_TEST_EXTERNAL_CMAKE we already have a few dashboards
that run the CMake test suite using a different generator/compiler
than was used to build CMake.  The tests that are independent of
the compiler/generator tend to be very small and very fast so it
does not hurt to run them again.
