I'm not sure whether it counts as a bug (I have not reported one about 
it). It would certainly be nice if Qt would tell us in the build system 
that it pulled it in from 3rd-party so that we can error out in CMake. 
Apart from that there is probably not much to do. I always thought that 
it doesn't matter as distros don't like 3rd-party and will just build Qt 
against the system library ;-)
