# McRogueFace Build Makefile
# Usage:
#   make              - Build for Linux (default)
#   make windows      - Cross-compile for Windows using MinGW (release)
#   make windows-debug - Cross-compile for Windows with console & debug symbols
#   make clean        - Clean Linux build
#   make clean-windows - Clean Windows build
#   make run          - Run the Linux build
#
# WebAssembly / Emscripten:
#   make wasm         - Build full game for web (requires emsdk activated)
#   make wasm-game    - Build game for web with fullscreen canvas (no REPL)
#   make playground   - Build minimal playground for web REPL
#   make serve        - Serve wasm build locally on port 8080
#   make serve-game   - Serve wasm-game build locally on port 8080
#   make clean-wasm   - Clean Emscripten builds
#
# Packaging:
#   make package-windows-light  - Windows with minimal stdlib (~5 MB)
#   make package-windows-full   - Windows with full stdlib (~15 MB)
#   make package-linux-light    - Linux with minimal stdlib
#   make package-linux-full     - Linux with full stdlib
#   make package-all            - All platform/preset combinations
#
# Release:
#   make version-bump NEXT_VERSION=x.y.z-suffix
#     Tags HEAD with current version, builds all packages, bumps to NEXT_VERSION
