title: Build Libevent with OpenSSL
body: <p>Tell me please, i am trying to build Libevent for Windows using Cmake GUI, I select the libevent folder and click - configure. But, cmake reports an error:</p>
  <blockquote>
  <p>Could NOT find OpenSSL, try to set the path to OpenSSL root folder in
  the   system variable OPENSSL_ROOT_DIR (missing:
  OPENSSL_CRYPTO_LIBRARY) (found   version &quot;1.1.1i&quot;)</p>
  </blockquote>
  <p>Let me ask you two questions:</p>
  <ul>
  <li>I understand that I have to show the Cmake the path to OpenSSL.
  I found a similar question: <a href="https://stackoverflow.com/questions/16248775/cmake-not-able-to-find-openssl-library">CMake not able to find OpenSSL library</a></li>
  </ul>
  <p>Where it says what is needed:</p>
  <blockquote>
  <p>set the variables below:</p>
  <p>OPENSSL_ROOT_DIR=D:/softwares/visualStudio/openssl-0.9.8k_WIN32
  OPENSSL_INCLUDE_DIR=D:/softwares/visualStudio/openssl-0.9.8k_WIN32/include
  OPENSSL_LIBRARIES=D:/softwares/visualStudio/openssl-0.9.8k_WIN32/lib</p>
  </blockquote>
  <p>But I just can't figure out how to do this in CMake GUI.</p>
  <ul>
  <li>and i don't understand why the error says about openssl version 1.1.1i. Why exactly - &quot;1.1.1i&quot; ?</li>
  </ul>
