+# Locate SDL library
+# This module defines
+# SDL_LIBRARY, the name of the library to link against
+# SDL_FOUND, if false, do not try to link to SDL
+# SDL_INCLUDE_DIR, where to find SDL.h
+#
+# This module responds to the the flag:
+# SDL_BUILDING_LIBRARY
+# If this is defined, then no SDL_main 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 SDL_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 -lSDLmain 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 SDL_LIBRARY_TEMP in your configuration
+# and no SDL_LIBRARY, it means CMake did not find your SDL library 
+# (SDL.dll, libsdl.so, SDL.framework, etc). 
+# Set SDL_LIBRARY_TEMP to point to your SDL library, and configure again. 
+# Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this value
+# as appropriate. These values are used to generate the final SDL_LIBRARY
+# variable, but when these values are unset, SDL_LIBRARY does not get created.
+#
+#
+# $SDLDIR is an environment variable that would
+# correspond to the ./configure --prefix=$SDLDIR
+# used in building SDL.
+# 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 SDLmain 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 
+# SDL_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 SDL/SDL.h to just SDL.h
+# This needed to change because "proper" SDL convention
+# is #include "SDL.h", not <SDL/SDL.h>. This is done for portability
+# reasons because not all systems place things in SDL/ (see FreeBSD).
