# Configuration for creating a Darwin app folder.
# In practice, this is used for Mac OS X; I'm not sure all of it applies to
# other Darwin-based systems.
#
# TODO:
# This Makefile does two things:
# - sets SET_WINDOW_ICON to false, so app folder icon is used
# - sets flags for linking non-platform libs statically
# However, these should be two independent choices:
# - executable intended as standalone vs intended for use in app folder
# - link non-platform libs statically vs dynamically
#
# The following libraries are standard on Mac OS X:
# - libxml2
# - OpenGL
# - TCL
# - zlib
# The following libraries will be linked statically:
# - libpng
# - SDL
# - SDL_image
# - GLEW
# No libraries will be included in the app folder.
# The following libraries will be disabled:
# - Jack
