With
https://github.com/iree-org/iree/pull/9854, a few CMake options, command line flags, file names, and environment variables are being renamed.
The PR has more details, but generally - "dylib-llvm-aot" should now be "llvm-cpu". The old name will be removed soon, so please plan for that and update any references you have to the old environment variables, CMake options, etc.
This better reflects how compiler target and runtime HAL drivers, devices, and executable loaders are set up. There was a similar change on the runtime side last month, clarifying runtime HAL driver names "local-sync" and "local-task":
https://github.com/iree-org/iree/pull/9399. Expect a few more changes to the primary IREE project in the coming weeks to tidy up any remaining references to the old names.
