# 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
 | 
			
		||||
# SDL2_DLL_DIR, where to find SDL2.dll if it exists
 | 
			
		||||
#
 | 
			
		||||
# 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).
