How to control c++ std locally?

[ianhi]

Hi @marktsuchida I was trying to get this to build locally (in the context of working on MMCore) and I keep running into the below error. Is there an easy way you can recommend to force this to be c++14?

Ahh it seems I can do: export CFLAGS='-std=c++14' but it does seem that this should be embedded somewhere in the definition of the build?
