title: Installing OpenSSL library for Xcode
body: <p>I have installed OpenSSL in xcode for receipt validation, but it doesn't work.</p>
  
  <p>I download <code>openssl.xcodeproj</code> and <code>openssl-1.0.1f</code>. I extract openssl-1.0.1f and add <code>openssl.xcodeproj</code> to my project. </p>

  <img src="https://i.stack.imgur.com/zPpmB.png" alt="inserted openssl.xcodeproj"></p>
  
  <p>I edit the <code>Header Search Path</code> to : </p>
  
  <pre><code> /Users/marko/Documents/Razvoj/BIView\ Mobile\ New\ Version/openssl/include/openssl
  </code></pre>
  
  <p>I added <code>libcrypto.a</code> in <code>Target Dependencies</code> under Build Phases</p>
  
  <p>and added <code>libcrypto.a</code> in <code>Link Binary With Libraries</code></p>
  
  <p>as was described in <a href="http://atastypixel.com/blog/easy-inclusion-of-openssl-into-iphone-app-projects/" rel="noreferrer">http://atastypixel.com/blog/easy-inclusion-of-openssl-into-iphone-app-projects/</a>.</p>
  
  <p>But when I build project it stops with error : </p>
  
  <pre><code>clang: error: no such file or directory: '/Users/ .... -bmgslnakszsfovecplbzoslykrxo/Build/Products/Debug-iphoneos/libcrypto.a'
  </code></pre>
  
  <p>Why ?</p>
