Comment 0 for bug 1777994

I suspect this means there should be another package, libxcb-xinput-dev perhaps?

I already did sudo apt install "libxcb*dev" to get all related dev packages, but none of them provide xcb/xinput.h.

The result is that when building Qt from source, it's necessary to use a copy of this file which Qt provides (qtbase/src/3rdparty/xcb/include/xcb/xinput.h), because it's missing from the system. So if you don't give the option -qt-xcb to configure, then Qt will be built without multi-touch support.
