Shouldn't this be _one_ SDL module? Although many other modules includes more 
than one library, SDL is the only one that needs more than one macro for it. 
This is not consistent.

[CMake] Module to detect SDL_GFX

[Oliver Dole]

Hello,

You will find as an attachment a dummy cmake module which automates
SDL_GFX detection as it is already done for SDL_ttf, SDL_image...
This module is in fact a copy and paste with of course modifications
of SDL_image module done by Eric Wing.
Note that I have only tested it on Linux... So if anybody can confirm
that it works for other OS.

Regards,

# This module defines
#  SDLGFX_LIBRARY, the library to link against
#  SDLGFX_FOUND, if false, do not try to link to SDL
#  SDLGFX_INCLUDE_DIR, where to find SDL/SDL_gfxPrimitives.h
#
# $SDLDIR is an environment variable that would

# On OSX, this will prefer the Framework version (if found) over others.
