generated engine: FILE_SETS requires CMake 3.23, currently not widely available
CMake 3.23 is not widely available yet. It would therefore be desirable to refrain from the SET_FILE feature and instead use older mechanisms.
Ideally, we go back to features included in cmake 3.16.3 (Ubuntu LTS 20.04 LTS) or 3.22.1 (Ubuntu 22.04 LTS).
