`Could not build Objective-C module 'cmark_gfm_extensions'` compiler errors

[Nikolozi]

My Xocde project is a mix of C, C++ and Swift. And adding these to my Package.swift

.package(url: "https://github.com/swiftlang/swift-markdown.git", branch: "main")
....
.product(name: "Markdown", package: "swift-markdown")

And then simply adding import Markdown in any of my Swift files leads to these errors in Xcode.

Could not build Objective-C module 'cmark_gfm_extensions'
Import of C++ module 'cmark_gfm' appears within extern "C" language linkage specification
Import of C++ module 'std_stdint_h' appears within extern "C" language linkage specification

Any clues on what might be going on?

I asked around and it looks like this is an issue in swift-cmark - even though the code in cmark has extern "C" guards around it, apparently it should not use #include directives inside those blocks. swift-cmark doesn't have issues enabled, so i'll leave this issue here to track it. Thanks for the report!
