title: What happened to FindSDL2 in CMake?
body: <p>I use SDL2 in my game. I always was using custom FindSDL2.cmake, because there is no one in standard CMake set. However, some time ago posts about FindSDL2 did appeared. Example: <a href="https://www.reddit.com/r/opengl/comments/8vgba5/using_sdl_with_cmake/e1n81fj" rel="noreferrer">Reddit post</a>.</p>
  
  <blockquote>
    <p>If your cmake is new enough and it has FindSDL2.cmake file, you can do this:</p>
  </blockquote>
  
  <pre><code>find_package(SDL2 REQUIRED)
  </code></pre>
  
  <p>But when I download latest CMake (3.13.2), it doesn't include <code>FindSDL2.cmake</code>.</p>
  
  <p>What happened to it?</p>
