title: How can I get CMake to find my alternative Boost installation?
body: <p>I have installed the most recent version of Boost in <code>/usr/local</code> (with includes in <code>/usr/local/include/boost</code> and libraries in <code>/usr/local/lib/boost</code>) and I am now attempting to install Wt from source, but CMake (version 2.6) can't seem to find the Boost installation. It tries to give helpful suggestions about setting BOOST_DIR and Boost_LIBRARYDIR, but I haven't been able to get it to work by tweaking these variables.</p>
  
  <p>The most recent error message that I get is that it can't find the libraries, but it seems to indicate that it is using "/usr/local/include" for the include path, which isn't correct (and I can't seem to fix it). Is there a solution for this off the top of their head, or do I need to go mucking around inside CMake to figure it out?</p>
