# 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 compatibility 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).
