I’m trying to build my C++ CMake project using Clang-12 instead of GCC-10 but compilation breaks on the stage of trying to compile simple program with error

I am using CUDA 11.4.3 on Ubuntu 20.04.3 LTS on WSL. I saw in documentation Installation Guide Linux :: CUDA Toolkit Documentation that Clang 12 is a supported compiler for this version of Ubuntu. Can you help me, please, to fix my build with Clang12?
