I had same issue with ubuntu 20.04 LTS while compiling from source, just remove libqt4-dev from list of installed packages and it worked, it seems like libqt4-dev is not really a requirement? 🤔

Same with me, the instructions here say I need libqt4-dev:
https://github.com/debauchee/barrier/wiki/Building-on-Linux

But when I removed that package from the list then the build worked. Do those instructions need to be updated? Is there another package I needed instead that I happened to already have?
