Exactly the same issue as asked here:
https://devtalk.nvidia.com/default/topic/950328/cant-install-pcl-point-cloud-with-cuda-help/

Can anybody help please?

Cheers

Did you solve this problem?

[hanshammel1337]

I solved this by changing line 2073 in cuda_compile_generated_NPP_staging.cu
https://github.com/PointCloudLibrary/pcl/blob/master/gpu/people/src/cuda/nvidia/NPP_staging.cu#L2073
to #if ((defined __CUDA_ARCH__) && (__CUDA_ARCH__ < 200))

I found the solution here https://devtalk.nvidia.com/default/topic/950328/cant-install-pcl-point-cloud-with-cuda-help/

CUDA 8.0.44, GCC 5.4 (Ubuntu 16.04 LTS), Arch 6.1

I didn't check if the people module works correctly, but the build is fine now. Maybe a pull request can be created for this.
