# - Locate the SDL_net library
# This module defines
# SDLNET_LIBRARY, the library to link against
# SDLNET_FOUND, if false, do not try to link against
# SDLNET_INCLUDE_DIR, where to find the headers
#
# $SDLDIR is an environment variable that would
# correspond to the ./configure --prefix=$SDLDIR
# used in building SDL.
#
# Created by Eric Wing. This was influenced by the FindSDL.cmake
# module, but with modifications to recognize OS X frameworks and
# additional Unix paths (FreeBSD, etc).
# On OSX, this will prefer the Framework version (if found) over others.
# People will have to manually change the cache values of
# SDLNET_LIBRARY to override this selection.
