title: Xcode 7.0.1 not finding files at header search path
body: <p>I am following <a href="https://nsrover.wordpress.com/2014/04/23/youtube-api-on-ios/" rel="nofollow noreferrer">this</a> tutorial for upload video to YouTube.<br><br>
  I cloned Google library and also added path to "Header Search Path" but still it is not taking files from that location and gives me error file not found.<br><br>
  Then as per <a href="https://stackoverflow.com/questions/16431341/xcode-is-not-using-header-search-path-to-find-my-header-files">this stackoverflow post</a> I added all that path to 'User Header Search Path' still it is not finding files.<br><br>
  I also select "YES" in ALWAYS_SEARCH_USER_PATHS but still it gives me error.<br><br>
  What I am doing wrong? why "Header Search Path" is not working? <br><br> I am following everything as per tutorial.</p>
