+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.
+
+KTOUCH_BUILD_WITH_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.
+
+- Move the checks to root CMakeLists.txt
+- Move finding Qt5X11Extras behind "NOT WITHOUT_X11" too
+- x11_helper is conditional on KTOUCH_BUILD_WITH_X11
+
+* backported to release/22.04
