If you clone ashpd and open it with vscode, it will properly find the ashpd-demo manifest but won't build because the meson.build won't be found in this case as it is in ashpd-demo subdirectory.

I think we should look at the last module, if it is of type path, get the absolute path based on that + the path of the manifest. If it is not, we need to come up with a different approach.
