CUDAcross platform macOS and linux

[the-code-samurai-97]

What is the best way to not see any errors when i do bazel build //... i am trying platforms but i still loading the rules cuda using https archive so it still give me error
While resolving toolchains for target //src/examples/cuda_example:kernel: No matching toolchains found for types @rules_cuda//cuda:toolchain_type.

Great question, macOS is not supported, then there should be a way to exclude cuda targets from all when you are building on the platfrom.

One way to add target_compatible_with = ["@platforms//os:<blahblah>"] to the target, but it is not scalable. This will be easy if you are developing a very small project with a few cuda targets.

Another way is to leverage if_cuda, it basically conditionally disable all cuda target on unsupported platfroms, but we need to improve it (if possible) so that it automatically excludes from all...
