Cannot build automatically with Gnome Builder
Following README instructions, I cloned the project using Builder and clicked run, but I got this error:

I was trying to clone and tinker with this app to learn how to make Rust GTK apps, so I don't really know what the cause could be or how to fix it. If this is expected, maybe it would be useful to add the needed steps to the README file.
Thanks a lot.
