# The Apple SDK for macOS 15.5, and the Mach-O tools of the host's LLVM: what
# the macOS port (make macos) links its programs against and joins them
# with. The SDK holds the frameworks (Cocoa, CoreAudio, IOKit and the rest)
# and their stub libraries; zig (component zig) brings the C library. Apple
# ships the SDK only inside Xcode and offers no download of it, so it comes
# from the mirror osxcross users share (github.com/joseluisq/macosx-sdks),
# pinned to the release's SHA-256; a copy of the same tarball put in
# toolchains/cache/downloads first (MacOSX15.5.sdk.tar.xz) is used instead.
# Its licence is Apple's (LICENSES.md). llvm-lipo joins each architecture's
# build into one universal file and llvm-libtool-darwin archives universal
# objects (make/support/macos/cc.sh, make/macos.mk).
