−# - Locate SDL2_net library
+
−# This module defines:
+
−#  SDL2_NET_LIBRARIES, the name of the library to link against
+
−#  SDL2_NET_INCLUDE_DIRS, where to find the headers
+
−#  SDL2_NET_FOUND, if false, do not try to link against
+
−#  SDL2_NET_VERSION_STRING - human-readable string containing the version of SDL2_net
+
−#
+
−# For backward compatiblity the following variables are also set:
+
−#  SDL2NET_LIBRARY (same value as SDL2_NET_LIBRARIES)
+
−#  SDL2NET_INCLUDE_DIR (same value as SDL2_NET_INCLUDE_DIRS)
+
−#  SDL2NET_FOUND (same value as SDL2_NET_FOUND)
+
−#
+
−# $SDL2DIR is an environment variable that would
+
−# correspond to the ./configure --prefix=$SDL2DIR
+
−# used in building SDL2.
+
−#
+
−# Created by Eric Wing. This was influenced by the FindSDL2.cmake
+
−# module, but with modifications to recognize OS X frameworks and
+
−# additional Unix paths (FreeBSD, etc).
