Unity builds are mostly for improving build speed. If you're just 
building Qt modules without actively working on the files then you 
should see build speed improvements. If you're actively working on a Qt 
module you don't want to use unity builds, because you don't want big 
chunks of the module being rebuilt just because you're working on one 
file. One thing we're hoping for is improved CI times with unity builds.


BR,

Joerg
