title: How to add #include in makefile?
body: <p>I want to build following source: <a href="https://bitbucket.org/portix/dwb/src" rel="nofollow">https://bitbucket.org/portix/dwb/src</a>. If I run <code>make install</code> I get:</p>
  
  <pre><code>In file included from dwbremote.c:19:
  ./dwbremote.h:22:10: fatal error: 'X11/Xlib.h' file not found
  #include &lt;X11/Xlib.h&gt;
           ^
  </code></pre>
  
  <p>So I added <code>CFLAGS += -I/opt/X11/include</code>to config.mk. But this didn't fix it. I'm getting the same error.</p>
  
  <p>EDIT: The header to include is at /opt/X11/include/X11/Xlib.h</p>
