wait a minute, WHY you installed the other PPAs than just "Applications" ? and why are you trying to build against the qt6.6-static, which is only applicable for the vee-one plugins, while on the launchpad.net build servers? you could build qtractor alright with all these, but it's just not advisable for you to take that path atm.
get rid of that: remove the qt6.6-static and libs ppa's, if any installed, please, they're completely unnecessary to the case at hand; and install all the above bulld-depends, making sure not a single one is missed.
