Sure. But the downside is only that the package would be larger for a 
few weeks until Qt6 is fixed.

This IMO doesn't justify spending more time on improving the workaround.

I am not sure if this is a one file problem. The nature of this problem 
is murky, it affects Qt6 meta-objects of all Qt6-based derived classes.


The right solution is to apply the workaround suggested in the linked 
bug report, but I don't want to apply pressure on people doing this 
since I am sure they are busy.


Other ports with USES=qt:6 might be affected as well.



Thanks,

Yuri

somewhere in CMakeLists.txt to only compile one file without optimizations.
