CMake 3.31 introduced the policy CMP0174 that triggers a warning if a single-value argument is passed to a function without a value. We did this doing this when forwarding arguments in code that doesn't use _qt_internal_forward_function_args yet, e.g. in qt_internal_add_app: qt_internal_add_executable(... TARGET_PRODUCT ${arg_TARGET_PRODUCT} ...) Forward the warning-triggering arguments with _qt_internal_forward_function_args now, because that only forwards used arguments. In the future, we can offload more forwarding work to the _qt_internal_forward_function_args command and simplify the forwarding code in qt_internal_add_app and qt_internal_add_tool. This patch only fixes the worst offenders for now. Pick-to: 6.8 Change-Id: Ie786691e4b236decf4c62f4dd0751ed76b721177 Reviewed-by: Alexey Edelev <alexey.edelev@qt.io>
