# 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).
