CMake Deprecation Warning at /home/bero/abf/llvm/BUILD/llvm-20.1.0-build/llvm-project-llvmorg-20.1.0/cmake/Modules/CMakePolicy.cmake:6 (cmake_policy):
The OLD behavior for policy CMP0116 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.
