If you use template, follow the description in the README.  This template should be placed anywhere outside NS-3/ndnSIM and will simply use the installed NS-3 to link to.

If you not using template, take a look for ndn-load-balancer, ndn-custom-apps, ndn-cxx-simple, ndn-simple-with-content-freshness, ndn-simple-for-nrt-helper examples organization (i.e., .cpp file with main function and directory with code that is linked to the scenario).

While you certainly can do that, I would highly recommend to use the skeleton (https://github.com/named-data-ndnSIM/scenario-template <https://github.com/named-data-ndnSIM/scenario-template>).  It will speed up your compilation times and the default build script has more straightforward assumptions on where the code is.

With the skeleton scenario, you simply need to put it in extensions/ folder.  If you prefer using examples/ folder, then you need to create a folder, whose name is exactly as your scenario name, but without .cpp extension and put the code there.  Alternatively, you need to modify wscript in examples folder and add all necessary dependencies for your scenario.
