I thought the purpose of policies was to keep some backward compatibility feature, but allow users to select the new behavior. In this case, setting the behavior for new policies to OLD seems the most logical, especially when I asked for it with cmake_policy(VERSION). Now I'm forced to set this policy to OLD in order to not have a million warnings spam my team. This seems like a non-backward compatible decision. Is there a way to not have all these "developer" warnings on by default? I'm not sure how CMake distinguishes between who is a developer and who isn't. ----------------------------------------------------------------------------------- This email message is for the sole use of the intended recipient(s) and may contain confidential information.
