My gtk application ported to Windows via vcpkg crashes because it misses an essential resource ("image-missing.png"). As I found, that file is contained beneath gtk/icons and referenced in the file gtk/gtk.gresource.xml - which to my understanding should be compiled via glib-compile-resources and linked into the library. The CMakeLists.txt contained in vcpkg/ports/gtk does not mention any of this, so I assume it is simply not yet implemented.
