title: I can't access GLM
body: <p>I downloaded GLM from the site. First of all, I can't unzip the file, as it didn't come in .zip format. I used a zip unarchiver and it still did not produce an unzipped file. Regardless, I tried including a header search path but Xcode has this weird Debug/Release path. Don't know which to access, but I tried putting the path to the glm files on both Debug and Release. Still did not let me use glm files. Lastly, I tried putting the glm files directly into the project files, and it still did not let me use the files in glm. </p>
  
  <p>I looked at other posts on stack for the same problem, and they all said to include it into the header search path, but their format is different from mine. Idk, just need some really clear directions on this as everything is out of order.</p>
