Actually, that's not correct, sorry I wrote the explanation too quickly. What I described is actually REQUIRED_ALWAYS. REQUIRED_IF_USED means that if the policy behavior is hit (ie, relying on old CMP0011 behavior), *and* the code has cmake_policy(SET CMP0011 OLD) *then* they get an informative error. If they set the policy (with cmake_policy or with cmake_minimum_required), but already don't rely on OLD behavior, then there is no new error.
