Regarding the building resource in `Package.swift`

[FlickerSoul]

It looks like the module map file is usually referenced as <llvm_root>/llvm/include/module.modulemap and the line 17 in the Package.swift doesn't seem to locate the module map correctly. That is, the llvmModuleMapPath is resolved as <llvm_root>/llvm/include/llvm/module.modulemap and doesn't match where the module map usually is.

    guard let llvmHeaderPath = env["SWIFT_LLVM_BINDINGS_PATH_TO_LLVM_HEADERS"] else {
        print("please pass an environment variable to swift-package: " +
              "SWIFT_LLVM_BINDINGS_PATH_TO_LLVM_HEADERS " +
              "(e.g. swift/llvm-project/llvm/include)")
        return nil
    }
    let llvmModuleMapPath = "\(llvmHeaderPath)/llvm/module.modulemap". // line 17

I am quite new to LLVM and am very likely to be wrong. If without llvm is intended, I can open a pr to fix it. :)

@FlickerSoul sorry for a delayed reply!

You are correct, the modulemap was moved to a different path in the LLVM repo in llvm/llvm-project@24f36a2 but we haven't updated the paths in Package.swift.

If without llvm is intended, I can open a pr to fix it. :)

That would be appreciated, thanks!

Thank you for confirming that! I'll open a PR soon! :)
