title: Build OpenVPN with specific OpenSSL version
body: <p>Similar questions have been asked before, but the answers no longer seem to apply as the flags have changed for the configure script. I am trying to compile OpenVPN from the git source on Ubuntu 14.04.5 on both x86 and x64. I have OpenSSL 1.0.1t built and installed to /usr/local/ssl. I've tried various combinations of the configure options and the compiler seems to recognize since</p>
  
  <pre><code>./configure OPENSSL_LIBS="-L/usr/local/ssl/ -lssl -lcrypto" OPENSSL_CFLAGS="-I/usr/local/ssl/include/"
  </code></pre>
  
  <p>finishes with no errors, but <code>./configure OPENSSL_LIBS="-L/usr/local/ssl/" OPENSSL_CFLAGS="-I/usr/local/ssl/include/"</code> results in <code>configure: error: openssl check failed</code>. Once you do make and make install, it still reports the system version of OpenSSL: </p>

  <p>I know it has to be something simple, but I saw other users asking about this on the OpenVPN Forums with no responses as of yet.</p>
