+Subject: [PATCH] CMake: Use SDL2's official CMake package mechanism
+
+We shouldn't need to rely on a FindSDL2.cmake, as SDL2 comes with a
+CMake package definition that should be installed by the distro into a
+location where CMake can find it.
+
+Fixes #168.

+-# - Find SDL2 library and headers
+-# 
+-# Find module for SDL 2.0 (http://www.libsdl.org/).
+-# It defines the following variables:
+-#  SDL2_INCLUDE_DIRS - The location of the headers, e.g., SDL.h.
+-#  SDL2_LIBRARIES - The libraries to link against to use SDL2.
+-#  SDL2_FOUND - If false, do not try to use SDL2.
+-#  SDL2_VERSION_STRING - Human-readable string containing the version of SDL2.
+-#
+-# This module responds to the the flag:
+-#  SDL2_BUILDING_LIBRARY
+-#    If this is defined, then no SDL2_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 SDL2_LIBRARIES variable.
+-#
+-# Also defined, but not for general use are:
+-#   SDL2_INCLUDE_DIR - The directory that contains SDL.h.
+-#   SDL2_LIBRARY - The location of the SDL2 library.
+-#   SDL2MAIN_LIBRARY - The location of the SDL2main library.
