      4. You need to add <code class="computeroutput"><span class="identifier">libs</span><span class="special">\</span><span class="identifier">math</span><span class="special">\</span><span class="identifier">include_private</span></code>
      to your compiler's include path as the needed header is not installed in the
      usual places by default (this avoids a cyclic dependency between the Math and
      Multiprecision library's headers).
