# CMake 3.21 and above requests projects to specify cpu/arch compile and link flags explicitly in
# Armclang. Link: https://cmake.org/cmake/help/latest/policy/CMP0123.html
# It is aligned with current Armclang toolchain implementation.
# Explictly set this policy to NEW behavior to eliminate long warnings. It shall be set in root
# CMakeLists.txt otherwise project() will throw out the warnings.
