cudaSafeCall() Runtime API error : no CUDA-capable device is detected.

I'm using Ubuntu 16.04 machine and I've successfully build the code here, but I failed to run command ./demo, where I got the error:

/home/ee303/WORKSPACE/Super-pixels/gSLICr/gSLICr_Lib/engines/../../ORUtils/MemoryBlock.h(196) : cudaSafeCall() Runtime API error : no CUDA-capable device is detected.

My dependencies:

Ubuntu 16.04
Cmake 3.5.1
Cuda 9.1
OpenCV 3.4.0

Additionally, here's the output of cmake command:

ee303@ee303-All-Series:~/WORKSPACE/Super-pixels/gSLICr/build$ cmake ..

And here is the output of make command:

So what have been wrong?
