This policy should be checked at the call site that tries to access the LOCATION property, not the directory scope containing the target. Thread the caller context through cmTarget::GetProperty to use for checking the policy setting and emitting a diagnostic with proper backtrace. Extend the RunCMake.CMP0026 test with a cross-directory case.
