Create a CUDA/cpp makefile - makefile

Question

I am a newbie in CUDA and want to compile my first programms on a Jetson TK1.
I have searched the Internet and also this Site but dont found something, that was helpful for me.
I have found this example
http://bikulov.org/blog/2013/12/24/example-of-cmake-file-for-cuda-plus-cpp-code/
and tried to compile the CUDA example oceanFFT which runs with the sample Makefile.
http://developer.download.nvidia.com/compute/cuda/1.1-Beta/x86_website/samples.html#oceanFFT
I have changed this CMakeLists.txt a little bit, but I dont know if I did this correct.

LIST(APPEND CUDA_NVCC_FLAGS -gencode arch=compute_20,code=sm_20)
LIST(APPEND CUDA_NVCC_FLAGS -gencode arch=compute_30,code=sm_30)
LIST(APPEND CUDA_NVCC_FLAGS -gencode arch=compute_35,code=sm_35)
TARGET_LINK_LIBRARIES(lbmslv /usr/local/cuda/lib/libcudart.so ${MPI_LIBRARIES})
When I run this I get a lot errors with :
undefined reference to .. gl.., glew.., glut..
so, not linked to this Libraries.
What did I wrong?
My problem with the sample Makefiles is, that they are to complicate for my.
I have also tried to make the sample Makefile easier.

Is their anything else, I can make easier or shorter?
I have less experience in creating makefiles and looking for a general way to create some for CUDA. I hope you can help me.
