title: Trying to get CUDA working, sample can't find helper_cuda.h
body: <p>I just installed CUDA and have been following <a href="http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-mac-os-x/index.html" rel="noreferrer">http://docs.nvidia.com/cuda/cuda-getting-started-guide-for-mac-os-x/index.html</a></p>
  
  <p>Everything works up until I try to copy a sample code such as deviceQuery to ~/Desktop and compile.  </p>
  
  <p>I get the following errors at compile:</p>
  
  <pre><code>/Developer/NVIDIA/CUDA-5.5/bin/nvcc -ccbin g++ -I../../common/inc  -m64 -Xcompiler -arch -Xcompiler x86_64   -gencode arch=compute_10,code=sm_10 -gencode arch=compute_20,code=sm_20 -gencode arch=compute_30,code=sm_30 -gencode arch=compute_35,code=\"sm_35,compute_35\" -o deviceQuery.o -c deviceQuery.cpp
  deviceQuery.cpp:23:25: error: helper_cuda.h: No such file or directory
  deviceQuery.cpp: In function ‘int main(int, char**)’:
  deviceQuery.cpp:111: error: ‘SPRINTF’ was not declared in this scope
  deviceQuery.cpp:116: error: ‘_ConvertSMVer2Cores’ was not declared in this scope
  deviceQuery.cpp:206: error: ‘checkCudaErrors’ was not declared in this scope

  deviceQuery.cpp:241: error: ‘checkCudaErrors’ was not declared in this scope
  make: *** [deviceQuery.o] Error 1
  </code></pre>
  
  <p>The code will compile and run in the CUDA directory and it is clear that the compiler can't find helper_cuda.h, I can't find it either does anyone have a solution?</p>
