[CMake] CMake CUDA 3.8+/9 support as a first class language with out Visual Studio Support... err what?

[Brian J. Davis]

With simple stand alone cmake 3.9 project using

cmake_minimum_required(VERSION 3.9)
project(cmake_testing CXX CUDA)

I can get a simple app to compile.  It however fails to run with:

GPU Device 0: "GeForce GTX 960M" with compute capability 5.0

Current device is [0]
Current device is [0]
CUDA error at 
C:\projects\cmake\cmaketesting\v3.9\cuda_basic\src\cuda_basic_test.cpp:67 
code=46(cudaErrorDevicesUnavailable) "cudaMalloc((void **)&d_volume, size)"

When trying to call cudaMalloc.  When trying to actually use the device.

     checkCudaErrors(cudaMalloc((void **)&d_volume, size));

So I am right back I started in the new simple project.

I am able to complle and run SDK examples say nbody.

it can only be two things right???  compile args and runtime environment 
(dll paths).  right?  err well or gremlins.

NBody compile important bits:
