Hi Slavek, as a temporary solution, I would say let's set the use of OLD as you suggested and then file a bug report to adapt cmake scripts to the NEW way. This may require several changes (no idea how many or how few at the moment), so it would be better to leave it for after v14.0.0 is out. Nevertheless for the future we should do the switch from OLD to NEW, because it could be possible that sooner or later the OLD way would no longer be supported, no one knows. What do you think? Cheers Michele PS: the next 3 or 4 days I won't be around at all.
