    file(TO_CMAKE_PATH $ENV{BOOST_ROOT} BOOST_ROOT)
    if (MSVC)
      set(BOOST_LIBRARYDIR ${BOOST_ROOT}/lib64-msvc-12.0)
    else (MSVC)
      set(BOOST_LIBRARY_DIR $ENV{BOOST_ROOT})
    endif (MSVC)
    find_package(Boost COMPONENTS filesystem system program-options thread REQUIRED)
  endif (ADD_BOOST)
  </code></pre>
