Where would one find documentation around the SNAPCRAFT_* environment variables?
I was able to find what I wanted by using:
override-build: | env snapcraftctl build
But that’s a bit of a pain to do.
For context the parts install dir is empty after the build step thus there is nothing to stage/prime. I’m pretty certain its because I need to move something around in the build step, i.e. from $SNAPCRAFT_PART_BUILD/build/install/bin to $SNAPCRAFT_PART_INSTALL (so parts/juju-db/build/build/install/bin -> parts/juju-db/install/)
