opengym-module corresponds to src/opengym

Maybe you can refer to the 18th issue if you still get interested :)

I cannot get rid of this error on the MAC. By installing protoc version 3.18.0 I have been able to run on Ubuntu. But on the MAC i cannot get rid of the same error. At what stage of the build does "opengym-module.h" get generated?

On Ubuntu -

find . -name opengym-module.h -print
./build/ns3/opengym-module.h

On Mac -
Same command produces no results.

There is something in the file "src/opengym/wscript" that is not working. Maybe someone can help.

Error messages are of the sort -

In file included from ../scratch/interference-pattern/sim.cc:32:
../scratch/interference-pattern/mygym.h:26:10: fatal error: 'ns3/opengym-module.h' file not found
#include "ns3/opengym-module.h"
^~~~~~~~~~~~~~~~~~~~~~

After correctly installing "protobuf 3.18.0" and "zeromq", the above problem was resolved.
Also, I deleted the "build" directory, ran "waf configure" again and re-built.

Great to hear.
