title: Cmake doesn't find Boost
body: <p>I'm trying to configure a project using CMake, but it fails to find Boost libraries even though they are in the specified folder. I have specified <code>Boost_INCLUDE_DIR</code>, <code>Boost_LIBRARYDIR</code> and <code>BOOST_ROOT</code> , but I still get an error saying that CMake is not able to find Boost. What could be the reason of such error?</p>
