Comment:
Meson was removed, about python3-xdg and the other I didn't test building without them, the Setzer README clearly says:

> Run the following command to install prerequisite Debian packages:
> ```
> apt-get install [...] python3-xdg [...] xdg-utils
> ```

Are we sure they aren't nedeed? If so, I'll remove them
