Comment (by ryandesign):

 Replying to [comment:6 mascguy]:
 > upstream's cmake script is enabling `unknown-warning-option`, and that
 appears to be a bug: The comments suggests that they actually want to
 DISABLE that, but they enable it instead.

 Have you filed an upstream bug report or pull request about that?
