<screen><userinput>mkdir build &amp;&amp;
cd    build &amp;&amp;

meson --prefix=/usr -Dudev-dir=/lib/udev -Dtests=disabled .. &amp;&amp;

    <para>
      To test the results, issue: <command>ninja test</command>.
      To run additional tests, install

      the "-Dtests=disabled" option from the meson line above.
