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-gi gir1.2-gtk-3.0 gir1.2-gtksource-4 gir1.2-gspell-1 gir1.2-pango-1.0 gir1.2-poppler-0.18 gir1.2-webkit2-4.0 python3-xdg gettext xdg-utils
> ```

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