[swift-users] [swift-build-dev] Importing C system libraries

Given the effort behind wrapping all of the functionality in swift package manager into an API (libPackageManager) so that in the future it can be used by IDE style tools, I don't think you need to be seriously concerned. It's convenient for the swift package folks, especially while supporting Linux (which doesn't have the Xcode IDE) to utilize the CLI, and it embeds nicely into Xcode build scripts as an interim step (and there's a long history of that with clang, llbuild, etc).

I wouldn't call libPackageManager a stable API (and I suspect the SwiftPM team wouldn't either), but it's the right structure to support future interactions and IDE support - Xcode or other projects that want to leverage it.
