There seems to be no way to bypass the “download_and_extract” step in the build process.
I’m trying to write an ebuild for it because the upstream version is apparently buggy ( https:/ /forums.ankiweb.net/t/fedora-35-and-anki-2-1-47-updates-with-blank-anki-window/13431/2 ) and disabling sandbox sounds like a terrible idea.
However, there does not seem to be a way to use system dependencies for those out of cargo.
