This commit updates various CMake configuration files to simplify the check for Apple platforms. It replaces the `CMAKE_CXX_COMPILER_ID` check for `AppleClang` with the built-in `APPLE` variable across multiple targets (such as `ftd`, `mtd`, `cli`, and others). This ensures that Apple-specific linker and compiler flags (like `-Wl,-map` and `-Wimplicit-int-conversion`) are correctly applied when building on macOS, regardless of the specific compiler used. Additionally, this commit updates `CMakeLists.txt` to explicitly set the `CMAKE_AR` and `CMAKE_RANLIB` paths to the default system locations (`/usr/bin/ar` and `/usr/bin/ranlib`) when the `APPLE` variable is set.
OpenThread CLI Example
This example application exposes OpenThread configuration and management APIs via a simple command-line interface. The steps below take you through the minimal steps required to ping one emulated Thread device from another emulated Thread device.
1. Build
$ cd <path-to-openthread>
$ ./script/cmake-build simulation
2. Start node 1
Spawn the process:
$ cd <path-to-openthread>/build/simulation/examples/apps/cli
$ ./ot-cli-ftd 1
Generate, view, and commit a new Active Operational Dataset:
> dataset init new

Wait a few seconds and verify that the device has become a Thread Leader:
> state

2. Start node 2
Spawn the process:
$ cd <path-to-openthread>/build/simulation/examples/apps/cli
$ ./ot-cli-ftd 2
Configure Thread Network Key from Node 1's Active Operational Dataset:
> dataset networkkey dfd34f0f05cad978ec4e32b0413038ff
Done
> dataset commit active
Done
Bring up the IPv6 interface:
> ifconfig up
Done
Start Thread protocol operation:
> thread start
Done
Wait a few seconds and verify that the device has become a Thread Child or Router:
> state

Done
3. Ping Node 1 from Node 2
> ping fd3d:b50b:f96d:722d:7a73:bff6:9093:9117
