# This uses the multi-stage build feature of Docker to build the binaries for multiple architectures without QEMU.
# The first stage is responsible for building binaries for all the supported architectures (amd64 and arm64), and the
# second stage only copies the binaries for the target architecture.
# We leverage Zig and cargo-zigbuild for providing a cross-compilation-capable C compiler and linker.
