Warning 'couldn't find pc file' when using SwiftPM

[nkristek]

When importing Starscream version 3.1.1 (currently latest) using SwiftPM I get the warning couldn't find pc file. I tried version 3.1.1 and master branch, when using 3.1.0, the warning does not appear.

Steps to reproduce

• create new iOS project (File > New > Project > iOS > Single View App)
• add SwiftPM dependency (File > Swift Packages > Add Package Dependency...), select either exact version 3.1.1 or branch master
• build

Also have this warning. It's because of this issue in swift-nio-zlib-support:

apple/swift-nio-zlib-support#3

Of which starscream currently depends on.

I commented in the other two threads. I don't have the context on why streamscreeam uses swift-nio-zli-support, but you can "silence" this warning by installing pkg-config on the device that you are compiling on:

brew install pkg-config

This really isn't a fix but a workaround. Maybe it should be considered adding this to the documentation for this project? Or maybe evaluated how swift-nio-zli-support is being used?

Thank you for that workaround

Two and a half months later and it's still an issue... Do I really have to add this to the common issues page of our project? Or is there a proper fix?

Since 3.1.0 does not have this issue, is there any crucial functionality missing from the latest version?

This issue seems to come from swift-nio. Thus I will close this issue, thanks!
