* Caribou dependency was removed in v27 (fd1a771ef4)
* Atspi is optional since then, when Mutter is built with Pipewire support.

* UPower is used through D-Bus now (c53491f97d)
* xmllint does not seem to be used (maybe it was used for building GResource in the past)
* use pkg-config instead of alias
