title: Unable to find the requested Boost libraries
body: <p>Platform:macOS High Sierra</p>
  
  <p>Hello,
  I tried to use the method <strong><em>Building from source</em></strong> to install <a href="https://github.com/rdkit/rdkit" rel="nofollow noreferrer">RDkit</a>, there is something wrong when I entered <code>cmake ..</code>,the terminal shows that</p>
  
  <blockquote>
    <p>CMake Warning at 
    /usr/local/Cellar/cmake/3.12.0/share/cmake/Modules/FindBoost.cmake:1723 (message):
      No header defined for python-py36; skipping header check
    Call Stack (most recent call first):
      CMakeLists.txt:202 (find_package)</p>
    
    <p>CMake Error at /usr/local/Cellar/cmake/3.12.0/share/cmake/Modules/FindBoost.cmake:2044 (message):
      Unable to find the requested Boost libraries.</p>
    
    <p>Boost version: 1.67.0</p>
    
    <p>Boost include path: /usr/local/include</p>
    
    <p>Could not find the following Boost libraries:</p>
    
    <p>boost_python</p>
    
    <p>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.</p>
  </blockquote>
  
  <p>But I have added /usr/local/Cellar/boost/lib and /usr/local/Cellar/boost-python/lib to the ~/.bash_profile.
  My ~/.bash_profile is written like this:</p>
  
  <blockquote>
    <p>export RDBASE=/Users/wangzhicheng/Software/RDkit/rdkit-Release_2018_03_3</p>
    
    <p>export PYTHONPATH=$RDBASE</p>
    
    <p>export DYLD_LIBRARY_PATH=$RDBASE/lib:/usr/local/Cellar/boost/1.67.0_1/lib:/usr/local/Cellar/boost-python/1.67.0/lib:/usr/local/lib:/usr/local/Cellar/boost-python3/1.67.0_1/lib</p>
    
    <p>export PATH="/Users/wangzhicheng/anaconda3/bin:$PATH"</p>
  </blockquote>
  
  <p>By the way, I had already installed boost, boost-python3 by homebrew.</p>
  
  <p>So where is the problem?</p>
