Getting started with XCode and CUDA - xcode

Question

So far I was able to install CUDA and it works fine.
However, I have no idea how to set up XCode for CUDA. And the posts out there seem to be really outdated and full of missing links and files. Also XCode seem to have changed a lot since 2009.
To begin, If I create a new project should I choose "Empty" or "External Build System" or something else?

Answer 1

I suggest using CMake:
1) Install latest CMake from http://www.cmake.org/download/
2) Create CMakeLists.txt and main.cu:
CMakeLists.txt
cmake_minimum_required(VERSION 3.3)
project(cuda_test)
find_package(CUDA REQUIRED)
cuda_add_executable(cuda_test main.cu)
main.cu (taken from http://thrust.github.io/)
#include <thrust/host_vector.h>
#include <thrust/device_vector.h>
#include <thrust/generate.h>
#include <thrust/sort.h>
#include <thrust/copy.h>
#include <algorithm>
#include <cstdlib>
int main()
{
thrust::host_vector<int> h_vec(32 << 20);
std::generate(h_vec.begin(), h_vec.end(), rand);
thrust::device_vector<int> d_vec = h_vec;
thrust::sort(d_vec.begin(), d_vec.end());
thrust::copy(d_vec.begin(), d_vec.end(), h_vec.begin());
return 0;
}
3) Use CMake GUI or command line to create a Xcode project out of the above (the following uses the cmake command line)
cmake -G Xcode
