tests/conformance/cpp/CMakeLists.txt (PROTO's lane) compiles
core/generated/velox_proto.cpp directly while its comment claims it links
libveloxproto. Now that the veloxproto target exists it should link
velox::proto, with a TARGET-guarded fallback to the direct-compile for
standalone configures. Filed, not edited — not CORE's file.
