trying now, thanks.

gory detail here,
http://pkgs.fedoraproject.org/cgit/qt5-qtbase.git/tree/qt5-qtbase.spec

In short, we use

had been considering trying
-prefix /usr
to see if that would change matters

I'll check this too, thanks.  Though, I'm not sure this could possibly help, 
since cmake isn't used at all at buildtime when those cmake files get 
generated (does it?).
