#   @file
#     CMake project for building and running selected CHIP unit tests using
#     'nrfconnect' platform integration layer in CHIP and Zephyr
#     'native_sim[/native/64]' platforms. Note that certain design decisions behind
#     the native_sim platforms make them inapplicable for some unit tests,
#     hence only a subset of CHIP unit tests is listed in the project.
#     See: https://docs.zephyrproject.org/4.0.0/boards/native/native_sim/doc/index.html
#     for more details.
