@aztec/native is missing native files

Importing BBNativePrivateKernelProver

import { BBNativePrivateKernelProver } from "@aztec/bb-prover/prover";

..produces the following error:

Can you specify when you want this? Cos you are trying to do native proving and can't use the CLI?

@rahul-kothari

I have a list of executionSteps and want to generate a proof. How would I use the aztec CLI to achieve a similar thing. This is needed for TEE-Rex prover.

async function createClientIvcProof(executionSteps: PrivateExecutionStep[]) {
  const nativeProver = await BBNativePrivateKernelProver.new(
    {
      bbBinaryPath: path.join(os.homedir(), ".bb", "bb"),
      bbWorkingDirectory: path.join(os.tmpdir(), "bb-working-directory"),
      bbSkipCleanup: false,
    },
    null as any,
  );
  return await nativeProver.createClientIvcProof(executionSteps);
}

the workaround is to patch @aztec/bb-prover:

diff --git a/dest/prover/index.js b/dest/prover/index.js
