"The system cannot find the path specified" when building with faber on Windows 8 x64 and VS2015

[h4k1m0u]

I wanted to install faber in order to use it to build Boost.Python, itself required by OpenGM.

Faber installs normally without giving an error with python setupy.py install. But, when I go inside boost.python folder to try to build it with faber on Windows with Visual Studio 2015 (v14), I get the following error: The system cannot find the path specified.

Please note that this error doesn't happen when faber is called as a python script with python c:\Python37\Scripts\faber, and that faber and faber.bat both exist.
