We do bundle the Qt Accessibility library in our builds on Mac and Windows.
On Linux we don't control the Qt release (it's provided by the OS) so we
have less control.
The main issue with VoiceOver support is that Qt's accessibility
implementation on OS X is based on Carbon and not Cocoa. They promised
Cocoa support in Qt 4.8 but it didn't happen. I believe Qt 5.2 works with
VoiceOver but I haven't tried it.
We are gradually making the switch to Qt5. Mixxx already builds fine with
Qt 5.2 and I expect Mixxx 1.13 will be the first release that includes it
by default but we can produce alternate 1.12.0 builds with Qt 5.2.
Hopefully that will provide a temporary solution for people who want
VoiceOver support.
Thanks,
RJ
