Fun anecdote about that: at work we added a wrapper around nvcc to point it at the right compiler, and renamed the original "nvcc" binary to ".nvcc-wrapped". But nvcc looks at argv[0] to print out its name in the --version output, and it truncates anything after a period (presumably to handle things like "nvcc.exe"?). And CMake's CUDA detection looks at nvcc --version. So CMake went down a really weird path where it knew that nvcc existed but didn't really believe it was nvcc, which was extremely confusing until I looked at some log output and went "wait, why isn't nvcc printing its own name".
