我是CUDA的新手，想在Jetson TK1上编译我的第一个程序。 我搜索了互联网和本网站，但没有找到一些东西，这对我有帮助。 我找到了这个例子 http://bikulov.org/blog/2013/12/24/example-of-cmake-file-for-cuda-plus-cpp-code/ 并尝试编译使用示例Makefile运行的CUDA示例oceanFFT。 http://developer.download.nvidia.com/compute/cuda/1.1-Beta/x86_website/samples.html#oceanFFT
我已经改变了一点CMakeLists.txt，但我不知道我是否做到了这一点。

当我运行这个时，我得到了很多错误：
undefined reference to .. gl.., glew.., glut..
所以，没有链接到这个库。 我错了什么？
我对样本Makefile的问题是，它们会使我的复杂化。 我还尝试使Makefile示例更容易。

他们还有什么，我可以更容易或更短吗？
我在创建makefile和寻找为CUDA创建一些的一般方法方面经验较少。我希望你能帮助我。
