CMake 4.3 reports three policy warnings while configuring bundled Highway. Each exposes compatibility behavior that makes configuration less deterministic or defers failures. The warnings and fixes are: * `CMP0111 OLD behavior is deprecated`: Highway’s GTest workaround allows an imported target without a location to produce unusable build rules. ATS disables Highway tests, so this selects NEW and makes any incomplete imported target fail during generation. * `CMP0075 is not set`: Highway’s header checks ignore inherited CMAKE_REQUIRED_LIBRARIES under OLD behavior. ATS also leaves OpenSSL libraries and includes in the probe state after TLS checks. This selects NEW and removes those OpenSSL values before generic checks, so required libraries are honored without leaking TLS dependencies. * `CMP0077 is not set`: Highway’s option(BUILD_SHARED_LIBS) discards the normal value supplied by ATS under OLD behavior. This selects NEW to preserve the parent setting while HWY_FORCE_STATIC_LIBS keeps bundled Highway static.

CMake 4.3 reports three policy warnings while configuring bundled
Highway. Each exposes compatibility behavior that makes configuration
less deterministic or defers failures.
The warnings and fixes are:
CMP0111 OLD behavior is deprecated: Highway’s GTest workaroundallows an imported target without a location to produce unusable
build rules. ATS disables Highway tests, so this selects NEW and
makes any incomplete imported target fail during generation.
CMP0075 is not set: Highway’s header checks ignore inheritedCMAKE_REQUIRED_LIBRARIES under OLD behavior. ATS also leaves OpenSSL
libraries and includes in the probe state after TLS checks. This
selects NEW and removes those OpenSSL values before generic checks,
so required libraries are honored without leaking TLS dependencies.
CMP0077 is not set: Highway’s option(BUILD_SHARED_LIBS) discardsthe normal value supplied by ATS under OLD behavior. This selects
NEW to preserve the parent setting while HWY_FORCE_STATIC_LIBS keeps
bundled Highway static.
