This is zstd, packaged for Zig.
First, update your build.zig.zon:
# Initialize a `zig build` project if you haven't already
zig init
zig fetch --save git+https://github.com/allyourcodebase/zstd.git#1.5.7-2
You can then import zstd in your build.zig with:
const zstd_dependency = b.dependency("zstd", .{ .target = target, .optimize = optimize, }); your_exe.linkLibrary(zstd_dependency.artifact("zstd"));
