CMake missing files

[thomas-yung]

CUDA version: 10.2
CMake version: 3.16.3

I followed the instructions given and arrive at the following output
It seems the CMakeLists is directing CUDA to files that aren't there

I have seen that another user managed to get this working with CUDA 8 however I am unable to downgrade from CUDA 10 at the moment

I am new to CUDA so apologies if I am missing something obvious
Help is appreciated

Hello, sorry for the late response. Are you still experiencing the problems during CMake build generation? With what source version are you currently working with?

[thomas-yung]

Thanks for your reply, I was able to get around the issue by setting a more explicit path in CUDA/src/gpu/CMakeLists.txt (line 1)

SET (GPU_GPUNUFFT_SOURCES ${GPUNUFFT_SOURCES} ${GPUNUFFT_SRC_DIR}/gpu/precomp_kernels.cu)

I am using the most recent source (i.e. cloned the repo)
