Comment (by ra1nb0w):

 As always, thank you Ryan for your help ;-)

 I did many tests before reach this "not so good" solution. I though also
 to use subport, this should be the best way, but I didn't find a way to
 remove {{{Portgroup qmake5}}} from the subport without rewriting the cmds
 and doing messy code. qmake should find {{{libxavna}}} also from
 ${prefix}/lib therefore the build should work. Have you some suggestion?

 Generally, I don't like to use ''private'' functions.
