Thanks for the nice write-up!

I don't recall whether CTest currently defines behavior for a relative path
found in an add_test call within a CTestTestfile.cmake.  We will need to
check and define behavior as needed.  Such a change would be something to
do in a preparatory step.

Yes, we'll need exactly one of these when at least one test used the
CTEST_OUTPUT_DIRECTORY property.  IIUC, tests without that property
will just stay in the CMAKE_CURRENT_BINARY_DIR's CTestTestfile.

Thanks,
