makefile

# Very quick/dirty makefile for building the nanogui example1.cpp in emscripten
# Puts the result in the `build/` directory
#
# Makefile tips:
#
#   * GNU make wants tab indentation, will error on spaces
#   * `$@` means substitute the target
#   * `$<` means substitute first thing in dependency list
#   * `$^` means substitute everything in the dependency list
