title: Python package installation failed on windows 'io.h' / 'sys/mman.h' : No such file or directory
body: <p>I'm on windows 10 and trying to install mrpt for python (3.5). 
  <code>pip install git+https://github.com/teemupitkanen/mrpt/</code> returns</p>
  
  <pre><code>c:\python35\include\pyconfig.h(68): fatal error C1083: Cannot open include file: 'io.h': No such file or directory
      error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\bin\\cl.exe' failed with exit status 2
  </code></pre>
  
  <p>Tried to launch <code>C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat</code> as it said <a href="https://stackoverflow.com/questions/40018405/cython-cannot-open-include-file-io-h-no-such-file-or-directory">here</a>.  It added the file <code>io.h</code> file in the folder <code>C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\include</code> that i added to the system path. But i still have the same error, when lauching <code>pip install ...</code></p>
  
  <p>I also tried to launch the <code>pip install ...</code> from the <strong>Visual c++ 2015 x86 x64 Cross Build Tools Command Prompt</strong> but now, i have another error</p>
