Error

CMake Error at cmake/pcl_find_cuda.cmake:13 (enable_language):
  No CMAKE_CUDA_COMPILER could be found.

  Tell CMake where to find the compiler by setting either the environment
  variable "CUDACXX" or the CMake cache entry CMAKE_CUDA_COMPILER to the full
  path to the compiler, or to the compiler name if it is in the PATH.
Call Stack (most recent call first):
  CMakeLists.txt:383 (include)

Solution

Set the CUDACXX variable. In this case I'm using 10.2:

export CUDACXX=/usr/local/cuda-10.2/bin/nvcc

Make sure to change the cuda-10.2 to what matches your version. I have a cuda-10 folder as well as a cuda folder but just used cuda-10.2.
