- Cross toolchains: llvm-mingw-aarch64 (Windows ARM64; SDL3 staged from MSYS2's clangarm64 repo since SDL ships no MinGW ARM64 dev package) and clang-aarch64-linux-gnu (Linux ARM64; arm64 libc++/SDL3 via dpkg multiarch). - Distro images: Dockerfile.linux-arm64, Dockerfile.win-arm64, Dockerfile.debian and Dockerfile.debian-arm64 (Debian 13 with upstream CMake, whose 3.31 gate cannot enable import std). - Packaging via CPack: .deb for Ubuntu 26.04 and Debian 13 on amd64 and arm64 (dependencies derived by dpkg-shlibdeps), portable .zip/.tar.gz, and a Windows .msi built with wixl (msitools) straight from the Linux cross image. wixl 0.106 lacks arm64, so Windows/ARM64 ships the portable zip only. - CMake: parameterize the SDL3 MinGW triple, add install() + CPack config. - CI: build/package jobs for both arm64 targets and both Debian packages; existing Linux/Windows jobs now also emit the .deb / .zip + .msi. - scripts/: build-linux-arm64, build-windows-arm64, build-debian, build-debian-arm64.
