This was originally attempted by policy CMP0118, but its implementation did not cover all intended use cases. We fixed its documentation in commit 1dabbbb5e0 (CMP0118: Revise documentation to describe actual behavior, 2024-03-20). Add new policy CMP0163 to cover the remaining use cases. In particular, make the `GENERATED` property visible to `get_property` calls in other directories. In order to capture the original intention of CMP0118, define CMP0163's NEW behavior to also imply CMP0118's NEW behavior. Fixes: #25437 Fixes: #25058
