We splitted out the ui libs and tools to avoid the circular deps:
 avahi ->  gtk -> cups -> avahi

avahi-bookmarks is provided by avahi-ui-utils package

We currently have circular dependency avahi -> gtk -> cups -> avahi

We drop building the gtk tools to break this and can build those in
separate package.
