Misc: switch back to SDL Qt Quick and QML was an exciting experiment but it's definitely not enough flexible and easy to use for game development. Using SDL2 will let us focusing on our own drawing functions without any kind of overhead. While here, start massive cleanup.

1 # - Locate SDL_image library
2 # This module defines:
3 # SDL2_IMAGE_LIBRARIES, the name of the library to link against
4 # SDL2_IMAGE_INCLUDE_DIRS, where to find the headers
5 # SDL2_IMAGE_FOUND, if false, do not try to link against
6 # SDL2_IMAGE_VERSION_STRING - human-readable string containing the version of SDL_image
7 #
8 # $SDLDIR is an environment variable that would
9 # correspond to the ./configure --prefix=$SDLDIR
10 # used in building SDL.
11 #
12 # Created by Eric Wing. This was influenced by the FindSDL.cmake
13 # module, but with modifications to recognize OS X frameworks and
14 # additional Unix paths (FreeBSD, etc).
