title: Where to get liber.h file/package for Lua?
body: <p>I'm trying to install the lualdap via luarocks with <code>sudo luarocks install lualdap</code>, but I am greeted with</p>
  
  <pre><code>Installing https://luarocks.org/lualdap-1.2.4.rc1-0.src.rock
  
  Error: Could not find header file for LBER
    No file lber.h in /usr/local/include
  You may have to install LBER in your system and/or pass LBER_DIR or LBER_INCDIR to the luarocks command.
  Example: luarocks install lualdap LBER_DIR=/usr/local
  
  </code></pre>

  <li>I am on Lua 5.3.</li>

  </ul>

  <p>I've looked around for what rock file I need to download to get this lber.h file, but am not having any luck with it. How can I get this lber.h file?</p>
