title: How do I build sqlcipher?
body: <p>First, I completed the build using <code>mingw</code> and created the <code>sqlcipher.exe</code> file.
  By the way, there was a warning during the build.
  So, I doubt if I built it properly.</p>
  
  <p>Warning content:</p>
  
  <pre><code>$ make

  </code></pre>
  
  <p>especially,I think the sentence is a problem.
   </p>
  
  <p>Can I ignore the warning?
  I am worried that the <code>openssl</code> library is properly linked and built.
  Was it a good build?</p>
