libcpmt.lib(xthrow.obj) : error LNK2038: mismatch detected for '_MSC_VER': value '1600' doesn't match value '1800' in nms_gpu_mex.o

I am trying to run the project here https://github.com/ShaoqingRen/faster_rcnn and I am getting an error when I run the function faster_rcnn_build. Can someone tell me what that error means and how I can resolve it ?

This is the output

Compiling nms_mex
Building with 'Microsoft Windows SDK 7.1 (C++)'.
MEX completed successfully.

Before all the error appears

_MSC_VER is a value corresponding to the version of the Microsoft compiler that is being used. The 1600 is for Visual Studio 2010, and the 1800 is for Visual Studio 2013. So you are trying to link code that was compiled with the 2010 compiler with code that was compiled with the 2013 compiler. This version mismatch is causing the error.
