CMP0118-------The :prop_sf:`GENERATED` source file property is now visible in all directories.Whether or not a source file is generated is an all-or-nothing globalproperty of the source. Consequently, the associated ``GENERATED``property is now visible from any directory scope, not only from the scopefor which it was set.The ``OLD`` behavior of this policy is to only allow ``GENERATED`` to bevisible from the directory scope for which it was set. The ``NEW``behavior on the other hand allows it to be visible from any scope.This policy was introduced in CMake version 3.20. CMake version |release|warns when the policy is not set and uses ``OLD`` behavior. Use the:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
