Oops, sorry, I forgot to check the installation. GTK+ 3.18 did built, but it was built into `gtk-3.0` directory (the build scripts in the old repo seem to do so). But `CMakeLists.txt` remained unchanged. I noticed that recent versions install `gtk-3.18` and `gtk-3.20` dirs, so I'll change the build scripts to have `gtk-3.18` as a target directory.
