A *temporary workaround* is to manually edit /usr/lib/x86_64-linux-gnu/pkgconfig/gdk-3.0.pc (this is path on my 64bit system, use locate gdk-3.0.pc to find the file if this path is not present at your system) changing:
Requires.private: gio-unix-2.0 fontconfig x11 xext xinerama xi xrandr xcursor xfixes xcomposite xdamage wayland-client >= 1.0.0 xkbcommon >= 0.2.0 wayland-cursor cairo-xlib cairo pangoft2
to
Requires.private: gio-unix-2.0 fontconfig x11 xext xinerama xi xrandr xcursor xfixes xcomposite xdamage cairo-xlib cairo pangoft2
With that change most applications using GTK should build fine.
