As in wlroots: swaywm/wlroots#2953.
To build sway on my system with outdated wayland-protocols (1.20):
meson setup --force-fallback-for wayland-protocols build
Without the force-fallback, sway finds wayland-protocols from the system, which does not satisfy wlroots (>=1.21) and the setup fails without a good error message.
I'll add a note in the wiki if this is merged.
