how to use/include rename_exceptions.h, is there a detailed document talk about enable cmsis-compatible layer?

By default this file does not take effects, in final image i can't find replaced symbol., though default value of PICO_CMSIS_RENAME_EXCEPTIONS is 1.

In \src\rp2_common\cmsis\CMakeLists.txt, looks like PICO_CMSIS_CORE_PATH is defined by default.

set(PICO_CMSIS_CORE_PATH ${CMAKE_CURRENT_LIST_DIR}/stub)

Appendix F in https://datasheets.raspberrypi.org/pico/raspberry-pi-pico-c-sdk.pdf mentions:

Added CMSIS core headers
CMSIS core headers (e.g. core_cm0plus.h and RP2040.h) are made available via cmsis_core INTERFACE library. Additionally, CMSIS standard exception naming is available via PICO_CMSIS_RENAME_EXCEPTIONS=1

Thanks. Is there any example in pico-example has a demonstration of using this cmsis_core INTERFACE library?
