Unless your object is already in a dynamically linkable .so file linked
in to the application; you need to compile your application with
`pkg-config --cflags --libs gmodule-2.0`
This will ensure your applications globally visible symbols are
also exported (it boils down to the linker getting --export-dynamic)
Otherwise GtkBuilder has no way to search your type name
from your application.
