//! Build-time link configuration for the `oakapp` crate.
//!
//! M14 R3: the app links the oak* module crates as plain rlibs — there is
//! no `liboakengine` dylib to locate anymore. The only remaining link
//! concern is gpui's macOS backend: gpui_macos reaches the IOSurface API
//! through the `core-video` crate, which depends on `io-surface` with
//! `default-features = false` — that disables io-surface's `link` feature,
//! so nothing adds the IOSurface.framework to the final link and the
//! binary fails with undefined `_IOSurface*` symbols. The app's build
//! script is the single place that configures the macOS link, so link the
//! framework here.

fn main() {
	let os = std::env::var("CARGO_CFG_TARGET_OS").unwrap_or_default();
	if os == "macos" {
		println!("cargo:rustc-link-lib=framework=IOSurface");
		// The static FFmpeg's external codec libraries pull in `-lz`, and
		// on some machines that resolves to a package-manager copy whose
		// install name is @rpath/libz.1.dylib; without an LC_RPATH entry
		// the binary dies at launch ("Library not loaded"). Map the rpath
		// at the real system library.
