Hello, openfoam-2.2.0 builds fine without opendx available and seems to work fine too (at least its solvers). Thus opendx dependency should be made optional (or removed at all if not needed). Why this is crucial for me? I manage an HPC cluster and we do not want X or GL be there, but opendx requires both X and GL deps. What we need are openfoam solvers and this works perfectly without opendx present.
