# - Locate SDL_net library
# This module defines:
# SDL_NET_LIBRARIES, the name of the library to link against
# SDL_NET_INCLUDE_DIRS, where to find the headers
# SDL_NET_FOUND, if false, do not try to link against
# SDL_NET_VERSION_STRING - human-readable string containing the version of SDL_net
#
# For backward compatiblity the following variables are also set:
# SDLNET_LIBRARY (same value as SDL_NET_LIBRARIES)
# SDLNET_INCLUDE_DIR (same value as SDL_NET_INCLUDE_DIRS)
# SDLNET_FOUND (same value as SDL_NET_FOUND)
#
# $SDLDIR is an environment variable that would
# correspond to the ./configure --prefix=$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).
