Comment:
Yes I belive it's mandatory from https://docs.qtile.org/en/stable/manual/install/index.html#core-dependencies
`Qtile uses cairocffi for drawing on status bars and popup windows. Under X11, cairocffi requires XCB support via xcffib, which you should be sure to have installed before installing cairocffi, otherwise the needed cairo-xcb bindings will not be built.`
