This package used to support depending on zlib in the Swift Package Manager. It is no longer necessary for this use-case:
instead, you can use either systemLibrary targets or the SwiftPM linkerSettings flag. For examples of its use, see
CNIOExtrasZlib in swift-nio-extras.
This is a package just to be able to use zlib with SwiftPM.
To use this package, add this to your Package.swift in dependencies:
.package(url: "https://github.com/apple/swift-nio-zlib-support.git", from: "1.0.0"),
