I think that's fair enough, it's far from ideal.

I have asked on their Microsoft GitHub discussions page to see what they 
come back with. There are over 500 open issues though so I imagine I 
might have to wait a while. I don't really understand enough of the 
Fedora packaging syntax to really know what it's doing, but I think that 
failing all else we should just be able to copy the files to 
/usr/share/cmake and be done with it if there's no other workaround.
