title: building boost locale library on Windows
body: <p>I am trying to build the boost::locale library (<a href="http://cppcms.sourceforge.net/boost_locale/html/tutorial.html#a5771bce93e200c36f7cd9dfd0e5deaa" rel="nofollow">http://cppcms.sourceforge.net/boost_locale/html/tutorial.html#a5771bce93e200c36f7cd9dfd0e5deaa</a>) which is still in review for integration into boost but the cmake command throws up the following:</p>
  
  <pre><code>   D:\lib\boost_locale_v2.92\build&gt;cmake ..
  -- Looking for ICU libraries
  -- Looking for iconv
  -- Looking for Boost

  <p>I have got ICU and boost but can't figure out how to modify the out-of-box cmake script for boost::locale. Any help is appreciated</p>
