[CMake] CTest errors out when skipping a test

[Christoph Grüninger]

Hi CMake,
I am testing the SKIP_RETURN_CODE property for tests. Unfortunately
ctest error out when it found skipped tests. I expect ctest to not
fail, because skipped tests should be indicated, but are to some
extend expected and should still leave ctest passing.

Is this a bug? Or do I misunderstand the way CTest considers skipped
tests?

Thanks
Christoph
