It's good that we are checking for rubygem dependencies in cmake now, but I
think the checks should probably be mandatory when building the binding is
enabled rather than simply omitting the tests. Previously we could take a
source tarball and run 'cmake -DBUILD_[LANG}=ON && make test' and have
confidence that the language binding would be tested. With the tests being
(relatively) silently omitted when the test dependencies are not present,
it is much easier to get a false positive and think that we've tested
something when we haven't.
