-# Locate SDL2 library
-# This module defines
-# SDL2_LIBRARY, the name of the library to link against
-# SDL2_FOUND, if false, do not try to link to SDL2
-# SDL2_INCLUDE_DIR, where to find SDL.h
-#
-# This module responds to the the flag:
-# SDL2_BUILDING_LIBRARY
-# If this is defined, then no SDL2main will be linked in because
-# only applications need main().
-# Otherwise, it is assumed you are building an application and this
-# module will attempt to locate and set the the proper link flags
-# as part of the returned SDL2_LIBRARY variable.
-#
-# Don't forget to include SDLmain.h and SDLmain.m your project for the
-# OS X framework based version. (Other versions link to -lSDL2main which
-# this module will try to find on your behalf.) Also for OS X, this
-# module will automatically add the -framework Cocoa on your behalf.
-#
-#
-# Additional Note: If you see an empty SDL2_LIBRARY_TEMP in your configuration
-# and no SDL2_LIBRARY, it means CMake did not find your SDL2 library
-# (SDL2.dll, libsdl2.so, SDL2.framework, etc).
-# Set SDL2_LIBRARY_TEMP to point to your SDL2 library, and configure again.
-# Similarly, if you see an empty SDL2MAIN_LIBRARY, you should set this value
-# as appropriate. These values are used to generate the final SDL2_LIBRARY
-# variable, but when these values are unset, SDL2_LIBRARY does not get created.
-#
-#
-# $SDL2DIR is an environment variable that would
-# correspond to the ./configure --prefix=$SDL2DIR
-# used in building SDL2.
-# l.e.galup 9-20-02
-#
-# Modified by Eric Wing.
-# Added code to assist with automated building by using environmental variables
-# and providing a more controlled/consistent search behavior.
-# Added new modifications to recognize OS X frameworks and
-# additional Unix paths (FreeBSD, etc).
-# Also corrected the header search path to follow "proper" SDL guidelines.
-# Added a search for SDL2main which is needed by some platforms.
-# Added a search for threads which is needed by some platforms.
-# Added needed compile switches for MinGW.
-#
-# On OSX, this will prefer the Framework version (if found) over others.
-# People will have to manually change the cache values of
-# SDL2_LIBRARY to override this selection or set the CMake environment
-# CMAKE_INCLUDE_PATH to modify the search paths.
-#
-# Note that the header path has changed from SDL2/SDL.h to just SDL.h
-# This needed to change because "proper" SDL convention
-# is #include "SDL.h", not <SDL2/SDL.h>. This is done for portability
-# reasons because not all systems place things in SDL2/ (see FreeBSD).
