I need the following to make it compile:
diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt
index b403c8e4d0..66a549603d 100644

endif()
Research tells me that
"In modern Linux distributions (such as openSUSE running newer
toolchains like GCC 16), the variable HAVE_QT5_X11_EXTRAS might not be
detected or set properly during the CMake configuration phase. This
happens because modern Qt installations heavily isolate platform-
specific backends (Wayland vs. X11), or the detection logic fails to
find the legacy Qt5 X11 Extras module."
