Cmake compilation issues ns3

Hello all,

I encounter some compilation issues when compiling the ns3gym. The first is

In member function ‘virtual bool ns3opengym::BoxSpace::MergePartialFromCodedStream(google::protobuf::io::CodedInputStream*)’:
/home/soyo/wifi-ai/ns-3-dev/cmake-build-debug/contrib/opengym/messages.pb.h:2139:10: error: ‘value’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
 2139 |   dtype_ = value;

It is solved when I disable Werror.

The second is

This one is solved by removing the example folder and just compiling the models of ns3gym.

I am not so sure whether these are general problems or just happen in my setup (20.04-Ubuntu, ns-3.36.), and hopefully, there is some more elegant solution to them :).
