Experimenting basic C++ to Swift interop on Windows.

// swift-tools-version: 5.11
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "TestCxxToSwift",
    products: [
        // Products define the executables and libraries a package produces, making them visible to other packages.
        .library(
            name: "TestCxxToSwift",
            type: .dynamic,
            targets: ["TestCxxToSwift"]),
    ],
    targets: [
        // Targets are the basic building blocks of a package, defining a module or a test suite.
        // Targets can depend on other targets in this package and products from dependencies.
        .target(
            name: "TestCxxToSwift",
            swiftSettings: [.interoperabilityMode(.Cxx)]
        ),
        .testTarget(
            name: "TestCxxToSwiftTests",
            dependencies: ["TestCxxToSwift"], 
            swiftSettings: [.interoperabilityMode(.Cxx)]
        )
    ]

Building on Windows using DEVELOPMENT-SNAPSHOT-2024-01-30.
Build success but the C++ header is not generated.

Note: The same Package built on macOS generate the C++ header.

How to generate C++ header on Windows ?
