# ModelRouter GUI Windows builder
# Self-sufficient cross-compilation environment for the embedded llmsproxy core.
# Produces llmsproxy.exe (Go, windows/amd64, luajit tag) + lua51.dll (LuaJIT mingw build)
# inside a mounted workspace: cmd/gui/bin/{llmsproxy.exe,lua51.dll}
#
# Build:   docker build -t modelrouter/win-builder cmd/gui/docker/win-builder
# Usage:   make gui-win-docker   (or cmd/gui/scripts/dist-win-docker.sh)
#
# LuaJIT source is fetched from gitcode.com (CN-reachable mirror) with github
# fallback; pass --build-arg LUAJIT_REPO to override.
