# Build the distributable wispctl binaries into ./binaries from the Rust port
# (cli-rs). Binaries keep the legacy `wisp-cli-*` names so existing CI pipelines
# that curl them keep working.
#
# Linux builds are fully static (musl) so they run on any distro, nixery and
# busybox included; Windows is a self-contained GNU build. Both cross-compile
# with cargo-zigbuild. macOS builds link only the system frameworks.
#
# Needs: rustup targets below, zig, cargo-zigbuild, lipo (Xcode tools).
#   rustup target add x86_64-unknown-linux-musl aarch64-unknown-linux-musl \
#     x86_64-pc-windows-gnu x86_64-apple-darwin aarch64-apple-darwin
#   brew install zig && cargo install cargo-zigbuild --locked
