MarsSeed [1] filed a deletion request for unityx [2]: This is a bogus VCS package. Upstream needs cmake to build this, but the PKGBUILD here doesn't even have a build() function. Its declared dependencies are also quite out of alignment with upstream. The only thing this does is, it tries to execute a nonexistent Fish shell script inside the package() function. Maintainer is nonresponsive: @FabioLolix has already pointed out many packaging problems in 2022-11, but nothing happened. Better to delete this defunct, pointless package.
