Compilation error CUDA can't found

[spk921]

I did symbolic linke /usr/local/cuda to /usr/loca/cuda-9.0
Other application which use CUDA works fine and also exported CUDA_HOME.
And got below error which indicate can't find CUDA.

I'm also facing the same issue

My issue was that cuda was not installed (I thought it was).
