I’m trying to build Blender with Cycles CUDA binaries but get the following error. My suspicion is that CUDA does not like the GCC version that ships with Ubuntu 19.10 (9.2.1). I tried to mitigate that by setting CUDA_HOST_COMPILER to /usr/bin/gcc-8 in cmake but that throws the same error. I think that is because CUDA wants 8.2.0 and I have 8.3.0 installed?
How can I set clang as a compiler?

ERROR: No supported gcc/g++ host compiler found, but clang-8 is available.
Use ‘nvcc -ccbin clang-8’ to use that instead.
