_ROOT Version: 6.14.00
_Platform: Windows 10 64-bit
_Compiler: Visual Studio 2017
I am attempting to install root from source with bindings to an installation of Python 3.4 on my machine. I am using the x86 Visual Studio 2017 console to run the following CMake commands:
cmake "Visual Studio 15 2017" -DPYTHON_VERSION=3.4 -DPYTHON_EXECUTABLE=C:\Python34\python.exe -DPYTHON_INCLUDE_DIR=C:\Python34\include -DPYTHON_LIBRARY=C:\Python34\libs\python34.lib C:\Users\<name>\Desktop\root-6.14.00
and once that is completed:
cmake --build .
This results in a failed installation with the following errors.

My Python 3.4 installation is 32-bit. I have a couple other versions of Python installed on my machine but looking through the generated CMakeCache.txt file in my root directory I don’t see any other versions being considered. Could this be a mismatch between root version and Python version?
