Subject: [PATCH] Merge #19301: build: don't warn when doxygen isn't found

fa84edb93c85f7709fc53abf9c6daae5d1bb3b28 build: don't warn when doxygen isn't found (fanquake)

Pull request description:

  Doxygen isn't so important that we need to warn when it is missing. I'd
  assume it might even be missing more often than not for most builds.
