Module map for Zlib library

CZlib

Swift module maps for zlib, which allow you to use the zlib C library in your Swift project.

Usage

Add dependencies

Add the CZlib package to the dependencies within your application’s Package.swift file. Substitute "x.x.x" with the latest CZlib release.

.package(url: "https://github.com/Kitura/CZlib.git", from: "x.x.x")

Add CZlib to your target's dependencies:

.target(name: "example", dependencies: ["CZlib"]),

Import package

import CZlib

czlib's Issues

"warning: module 'Clibz' does not contain any sources."

Is this repo currently in use?

I was hoping to use it to link libz into a project in a Swift Package Manager-friendly way, so I added it to my dependencies with the following (in Package.swift):

  dependencies: [
    .Package(url: "https://github.com/IBM-Swift/CZlib", Version(0,1,1)),
  ]

But when building with swift build I get this warning:

warning: module 'Clibz' does not contain any sources.

and link errors that show that libz wasn't linked.
