# Locate SDL
# This module defines:
# SDL_FOUND - system has SDL
# SDL_INCLUDE_DIR - the SDL include directory

# The implementation is based on the standard FindSDL.cmake provided with CMake,
# but customized for targeting Emscripten only.

# These libraries are provided with Emscripten
SET(SDL_FOUND TRUE)

# This is the path where <SDL.h> is found
