From 68bee7bce59bed1def66518bc254ecf7ae8985c5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add CMake option to build WITHOUT_X11
We want to be able to build without X11 support even if some of the used
libraries may not work w/o X11 themselves yet or need to be built with
X11 support for other reverse dependencies.
HAVE_X11 already exists and is set automagically so far, but using
-DCMAKE_DISABLE_FIND_PACKAGE_X11 will break if any dependencies list X11
as required in their cmake config.
Introducing this option means there is no behavior change by default,
cmake will just skip finding X11 or adding unwanted features if the
option is enabled.
* backported to release/22.04
