Previously, when compiling cpu-only builds, I would get compiler warnings with functions like gpuMalloc(void** devPtr, size_t size) because the arguments devPtrffer and size are unused for non-gpu builds.
We avoid this by surrounding gpu functions by CHAI_GPUCC . These functions should not get called anyway for non-gpu builds
