title: "fatal error: mysql.h: No such file or directory" Compiling mod_auth_mysql-3.0.0
body: <p>I try to build mod_auth_mysql on my debian Wheezy and I got always this error:</p>
  
  <pre><code>mod_auth_mysql.c:269:19: fatal error: mysql.h: No such file or directory
  </code></pre>
  
  <p>I have never build package/mod before, I don't understand what I'm doing wrong. I have followed <a href="http://modauthmysql.sourceforge.net/BUILD" rel="nofollow">this documentation</a> and used this command line :</p>
  
  <pre><code>apxs2 -c -lmysqlclient -lm -lz mod_auth_mysql.c
  </code></pre>
