Project Files were generated with CMake for Visual Studio 14 2015.
Project File clRNG.sln. Building the Target "ALL_BUILD" fails because clRNG was not built before.
Building the "clRNG" Project fails with

Is it me or is it clRNG?
Platform Win 10 x64, Visual Studio 2015 (Configuration "Visual Studio 14 2015" is right, "Visual Studio 2015" won't work).

Am seeing this issue with 32-bit builds, but not 64-bit builds. Also not seeing this with older versions of Visual Studio. Seems to be unique to Visual Studio 2015 32-bit. Here's a log demonstrating the issue.

It appears the error is coming from the vendored copy of Random123, which is quite old. That said, I looked at a release from last year and it seems this portion of the code is unchanged. So there doesn't appear to be a strategy to handle this in recent versions of Random123 either. 😕
