Thank you very much, Douglas, for providing this solution. I will use your suggestions and compile the code.

One solution is to get the master branch from the repository. Alternatively, I think this is only a problem when compiling with the NEKTAR_USE_MESHGEN option. If you don't need this functionality, switching it off in cmake should help.
