Cuda 9 RC + VS2017 + CMake not working

Question

I'm trying to get a CUDA project to compile using CMake and Visual Studio 2017, but the build fails, details below.

System:
Windows 10 Pro x64
Visual Studio Enterprise 2017 Version 15.3.2
CUDA 9 RC (Version 9.0.103)
CMake 3.9.1 (Generator: Visual Studio 15 2017 Win64)

The dummy project:

CMakeLists.txt

cmake_minimum_required(VERSION 3.0.0)
project(vs17cuda)

# Cuda is always required
find_package(CUDA REQUIRED)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CUDA_NVCC_FLAGS "${CUDA_NVCC_FLAGS} -std=c++11" )

add_subdirectory(src)

src/CMakeLists.txt

cuda_add_executable(vs17cuda main.cu)
set_target_properties(vs17cuda PROPERTIES CUDA_SEPARABLE_COMPILATION ON)
target_link_libraries(vs17cuda ${CUDA_LIBRARIES})

src/main.cu

#include <cuda_runtime.h>

__global__ void DummyKernel()
{
    //do nothing
}

int main (int argc, char * argv[]) {
    DummyKernel<<<4, 4>>>();
}

Console output: (german messages translated to english)

How can the build be fixed?

It seems CUDA is now fully integrated with CMake. Functions from the FindCUDA package, such as cuda_add_executable now revert to the default add_executable. The details are spelled out in a recent blog post from NVIDIA: here. I cloned the Github repo linked to in that post, and it did work for me; though only for a 64-bit build.
