Description / Steps to reproduce the issue

cmake sim build on macOS is broken.

it's partly because of #14852.
it doesn't seem like the only issue though.

@cuiziwei1 can you take a look? thank you.

[cuiziwei1]

@yamt sorry about this, can you check if CONFIG_HOST_MACOS is enable?

[xuxin930]

Hi @yamt @cuiziwei1
CONFIG_HOST_MACOS is loaded after CMake generator execution completed.

However, this error occurs during the ToolChain file verification phase.
At this time, the generator has not yet been successfully executed.
So CONFIG_HOST_MACOS cannot be read

let change NOT CONFIG_HOST_MACOS to NOT APPLE

but can we unify the host check on both CMake and Makefile?
