I can stage a snap from the snap store like this:
parts:
audacity:
plugin: nil
stage-snaps:
- to amd64:
- audacity
How can i stage a snap that is not in the snap store, but “locally” on my harddrive?
Background:
To increase the build performance of my snap, i want to shift some long running task (which are stable and do not always have to be built again) to another snap.
