# CMake sub-project defining 'chip' target which represents CHIP library
# and other optional libraries like unit tests, built with 'nrfconnect'
# platform.
# Since CHIP doesn't provide native CMake support, ExternalProject
# module is used to build the required artifacts with GN meta-build
# system. It is assumed that find_package(Zephyr) has been called before
# including this file.
