hyperrogue/Makefile

# This Makefile works for Mac OS X (El Capitan), MinGW, and Linux.
# 
# Environmental vairables:
#   If you want to build with Glew, set
#     HYPERROGUE_USE_GLEW=1
#   If you want to use libpng, set
#     HYPERROGUE_USE_PNG=1
#
# For Mac OS X:
#   Run `brew install sdl12-compat sdl_gfx sdl_mixer sdl_ttf`
#   Run `brew install glew libpng` to install the optional dependencies
#   Run `make` to build HyperRogue as `./hyperrogue`.
#
# For MSYS2 and MinGW-w64:
#   To install SDL and other required libraries, run these commands
#   from the MSYS2 shell:
#       pacman -S mingw-w64-ucrt-x86_64-glew
#       pacman -S mingw-w64-ucrt-x86_64-SDL mingw-w64-ucrt-x86_64-SDL_mixer
#       pacman -S mingw-w64-ucrt-x86_64-SDL_ttf mingw-w64-ucrt-x86_64-SDL_gfx
#       pacman -S make
#   Then run "make" to build HyperRogue as ./hyperrogue.exe.
#
# For Ubuntu Linux:
#   Run "sudo apt-get install libsdl-dev" to install SDL in /usr/local.
#   Run "make" to build HyperRogue as ./hyperrogue.
