When building a simple OpenCV app in Visual Studio 2015 Update 3, with OpenCV 3.2, with target x64 (there are no x86 libs in 3.2 release), I get the following errors:
1>c:\program files (x86)\microsoft visual studio 14.0\vc\include\xtr1common(100): error C2737: 'std::is_same_v': 'constexpr' object must be initialized

Somehow I dont believe this is a problem with OpenCV, so I guess I am missing something in the build process or have something misconfigured. Any suggestions what should be changed are appreciated :)
I followed the following site http://opencv-srf.blogspot.com/2013/05/installing-configuring-opencv-with-vs.html when it comes to suggestions how to configure VS.
Adding source code, though I believe this is something related to configuration of the build, not to the source code:
#include "opencv2/opencv.hpp"
int main()
{
return 0;
}
I get the same errors when adding OpenCV 3.1 through Nuget as described in OpenCV via NuGet packages with Visual Studio 2015, how to configure? . Interesting enough it looks like similar errors where seen in completely different cases - Visual Studio 2015: C++ REST API (Casablanca) failing compilation in VS inlcudes/headers and where solved by reinstalling VS2015 from RC to full community edition. I am using VS2015 Enterprise Update 3 so I hope is not the root cause...
