  <p>Previously it was not able to find the boost libraries sp i manualy changed the CmakeList.txt library path with the path of boost_1_59_0 lib path. This path comes up in library option when i do cmake. But still boost_python3 is missing. I am new into this what i tried is just the result of google.
  Please help.</p>
