The project that I started this CI for shappimage has moved on to using my squashfuse-zig tools and the crappy build scripts I've been using here constantly break and I don't have the motivation to maintain them anymore so I will be archiving this repo.
If you need portable builds of squashfuse tools I'd recommend trying that repo, they should be fully compatable with the originals (with comparable performance). Otherwise, it should be fairly easy to build squashfuse from source using some code from the build scripts here.
