Thank you Sebastian for the quick reply :)

ACK.

Crystal clear, thanks.

Sure, ok.
So the right course of action is to just use the versioned vala $thing. I'm
pretty sure this will make transitions more difficult though, but we'll see.

Thank you very much. I'll go back fighting with cmake trying to use valac

Have a nice day,
