import PackageDescription

// SpiceMac — a native macOS SPICE client that opens Proxmox VE `.vv` consoles by
// wrapping (a forked) CocoaSpice.
//
// BUILD REQUIREMENTS:
//  * Full Xcode (not just Command Line Tools): CocoaSpice's renderer compiles a
//    .metal shader, which needs the Metal toolchain that only ships with Xcode.
//  * The native SPICE frameworks must be staged under ./Frameworks first:
//        ./scripts/fetch-sysroot.sh
//  * Build & bundle into SpiceMac.app with:  ./scripts/build-app.sh
//
// The pure-Swift libraries (VVConfig, SpiceInputMap) build and test on their own
// with just the toolchain — see their packages under Packages/.

// The native SPICE stack is linked as @rpath-relocatable *.framework bundles from
// the UTM sysroot (staged into ./Frameworks by scripts/fetch-sysroot.sh). UTM's
// lib/*.dylib are NOT relocatable (absolute CI install names), so we link the
// frameworks and embed them with @rpath. The version suffixes below track the
// sysroot's framework versions — update them if you fetch a different sysroot.
// Transitive deps (intl, pixman, openssl, opus, json-glib, …) load at runtime via
// @rpath from the embedded frameworks, so only the directly-referenced ones are
// listed here.
