+# Locate SDL2_ttf library
+# This module defines
+# SDL2_TTF_LIBRARY, the name of the library to link against
+# SDL2_TTF_FOUND, if false, do not try to link to SDL2_ttf
+# SDL2_TTF_INCLUDE_DIR, where to find SDL_image.h
+#
+# Additional Note: If you see an empty SDL2_TTF_LIBRARY_TEMP in your configuration
+# and no SDL2_TTF_LIBRARY, it means CMake did not find your SDL2_Image library
+# (SDL2_ttf.dll, libsdl2_image.so, SDL2_ttf.framework, etc).
+# Set SDL2_TTF_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_TTF_LIBRARY
+# variable, but when these values are unset, SDL2_TTF_LIBRARY does not get created.
+#
+# $SDL2 is an environment variable that would
+# correspond to the ./configure --prefix=$SDL2
+# 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" SDL2 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_TTF_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" SDL2 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).
+#
+# Ported by Johnny Patterson. This is a literal port for SDL2 of the FindSDL.cmake
+# module with the minor edit of changing "SDL" to "SDL2" where necessary. This
+# was not created for redistribution, and exists temporarily pending official
+# SDL2 CMake modules.
+# 
+# Note that on windows this will only search for the 32bit libraries, to search
+# for 64bit change x86/i686-w64 to x64/x86_64-w64
