# - Find SDL library
# Find the native SDL includes and library
# This module defines
#  SDL2_INCLUDE_DIRS, where to find SDL.h, Set when SDL2_INCLUDE_DIR is found.
#  SDL2_LIBRARIES, libraries to link against to use SDL.
#  SDL2_ROOT_DIR, The base directory to search for SDL.
#                This can also be an environment variable.
#  SDL2_FOUND, If false, do not try to use SDL.
#
# also defined, but not for general use are
#  SDL2_LIBRARY, where to find the SDL library.
