title: CMake error when compiling out of tree model in gnu radio
body: <p>I have a problem and I can't seem to find a solution to it. I am building a project using <code>gnuradio</code> and in the process of building an OOT module i always get the following error after <code>$cmake ../</code> (I followed the instruction from the GNU site though)</p>
  
  <blockquote>
    <p>$ cmake ../
    -- Build type not specified: defaulting to release.
    -- Could NOT find Boost 
    CMake Error at CMakeLists.txt:63 (message): 
    Boost required to compile trial</p>
    
    <p>-- Configuring incomplete, errors occurred!</p>
  </blockquote>
  
  <p>Please any help will be deeply appreciated (And please I am a noob so kindly have it easy on me).</p>
