    <para>
      For security reasons, running the server as an unprivileged user
      and group is strongly encouraged. Issue the following (as
      <systemitem class="username">root</systemitem>) to create the
      user and group:
    </para>

<screen role="root"><userinput>groupadd -g 40 mysql &amp;&amp;
useradd -c "MySQL Server" -d /srv/mysql -g mysql -s /bin/false -u 40 mysql</userinput></screen>

    <para>
      If the MySQL server is not needed, it is possible to build only the
      client libraries of MySQL. To do this you need to add
      <parameter>-DWITHOUT_SERVER=ON</parameter> to the <command>cmake</command>
      command below.
    </para>

    <para>
      MySQL contains an embedded server library. By default, it is built as a
      statically linked library, <filename>libmysqld.a</filename>, but by
      applying the optional patch, a shared version of this library can be built.
      The library is needed by certain applications, such as
      <application>Amarok</application> and it is recommend to use the shared
      libraries whenever it is possible.
    </para>

    <para>
      There are numerous options available to
      <command>cmake</command>. Check the output of the `<command>cmake .
      -LH</command>` for additional customization options. See the <ulink
      url="http://dev.mysql.com/doc/refman/5.6/en/source-configuration-options.html">
      MySQL Documentation</ulink> for a full listing of all options.
    </para>

    <para>
      If you want to build shared version of the embedded server library, apply
      the following patch:
    </para>
