SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***
kde-gtk-config uses GtkPlug for previewing, which is an X11-specific class.  ${ROOT}/gtk3proxies/preview3.c includes gtkx.h. However, CMake only searches for the generic gtk+-3.0 package-config file. If GTK+3 is built without X11 support, kde-gtk-config fails to compile.

STEPS TO REPRODUCE
1. switch to an X11-free version of GTK3 and its development files.
2. attempt to build kde-gtk-config.

OBSERVED RESULT
1. CMake configuration succeeds.
2. compilation fails at  ${ROOT}/gtk3proxies/preview3.c

EXPECTED RESULT
CMake searches for gtk+-x11-3.0.pc and throws an error if it is absent.
