Please extend the topic with updates to the test suite to cover the
new option.  Even if it is too hard to test that the independent
build behavior works we at least need to verify that using the
option does not break anything.

Also please add a RunCMake.ExternalProject test with a case to
verify that this message appears:

+        message(AUTHOR_WARNING "Using NO_DEPENDS for \"${step}\" step  might break parallel builds")

Also remove extra indentation from the above-quoted line.

Thanks,
