That's expected, only the subproject git submodule is supported. I'll bump it once wlroots 0.15.0 is released, but we might need some unreleased wlroots changes again at some point, and then 0.15.0 would stop working.

Done in 11f89c1.

Still fails here:

src/wlserver.cpp:26:10: fatal error: 'wlr/backend/noop.h' file not found
#include <wlr/backend/noop.h>
         ^~~~~~~~~~~~~~~~~~~~

According to CI logs noop.h likely comes from system wlroots-0.14.1-2 package:

[emersion]

Right, we install wlroots system-wide as a cheap way to bring all of its deps. Maybe we should explicitly install the deps instead.

Anyway, fixed in c1958be.
