# A simple makefile for CUDA projects.
# 
# This is much shorter then the default makefile, and is so by making the following assumptions:
# 1) The CUDA SDK is installed to ~/NVIDIA_CUDA_SDK
# 2) CUDA is installed to /usr/local/CUDA
# 3) The project does not use openGL/DirectX
# 4) You are on linux.
# 
# Add source files here

# Cuda source files (compiled with cudacc)
