title: cmake is using the wrong cboost libs
body: <p>i try to compile a program with cmake, but I got stock with this error:</p>
  
  <pre><code>  Unable to find the requested Boost libraries.
  
    Boost version: 1.34.1
  
    Boost include path: /usr/include
  
    Detected version of Boost is too old.  Requested version was 1.37 (or
    newer).
  
    The following Boost libraries could not be found:
  
            boost_program_options
            boost_filesystem
  
    No Boost libraries were found.  You may need to set Boost_LIBRARYDIR to the
    directory containing Boost libraries or BOOST_ROOT to the location of
    Boost.
  </code></pre>
  
  <p>I installed already the new boost package under /home/dev/boost_1_45_0.</p>
  
  <p>But always when I try to run cmake again I get still the same error.</p>
  
  <p>I also set </p>
  
  <pre><code>export BOOST_ROOT=/home/dev/boost_1_45_0
  </code></pre>
  
  <p>But when I execute <code>cd ${BOOST_ROOT}</code> I'm in the right folder.</p>
  
  <p>Can anybody help me? Thanks!</p>
