    <p>Error: Failed finding Lua library. You may need to configure LUA_LIBDIR</p>
  </blockquote>
  
  <p>Both my config files look like this:</p>
  
  <pre><code>    rocks_trees = {
     { name = "user", root = home .. "/.luarocks" };
     { name = "system", root = "/usr/local" };
  }
  lua_interpreter = "lua5.3";
  variables = {
     LUA_DIR = "/usr/include/lua53";
     LUA_BINDIR = "/usr/bin/lua53";
  </code></pre>
  
  <p>}</p>
  
  <p>Any help is appreciated!</p>
