Fix -> WARNING: nvcc not in path with CUDA

i was installing Pycuda in my mac and when i compile i get this error. I did install CUDA from nvidia and it seems to be a path problem.

*** WARNING: nvcc not in path.

i fixed it by assigning paths to the CUDA library

export PATH=${$PATH}:/usr/local/cuda/bin
export CUDA_ROOT = /usr/local/cuda/

and then finally

python setup.py build 
sudo python setup.py install

Thats it!
