#     CMake sub-project defining 'chip' target which represents CHIP library
#     and other optional libraries like unit tests, built with 'mbed'
#     platform.
#     Since CHIP doesn't provide native CMake support, ExternalProject
#     module is used to build the required artifacts with GN meta-build
#     system.
