A small note on xkbcommon: Qt/xcb also requires it. Please make sure 
that Qt
is built with a system xkbcommon, otherwise it picks the one bundled in 
party and that has resulted in crashes in KWin in the past if KWin is 
with a system xkbcommon.

Please note that libinput support in KWin does not introduce any 
dependency on logind or logind-shm. It only imposes a runtime 
dependency. The
same runtime dependency is also required by the drm backend. So this 
dependency should not hinder anyone to build dep on libinput.

The logind integration is build unconditionally and also run 
on both x11 and wayland.
