Harald Fernengel b57681dc34 FetchContent: Fix protobuf example to avoid CMP0077 warning ...

The protobuf example would raise a "Policy CMP0077" warning and
protobuf tests would still be built, e.g. setting the variable is
ignored in latest CMake. Set an INTERNAL cache variable instead so
that CMP0077 warnings won't be triggered.
