ngsxfem tries to build ngsolve as part of the building process and hence requires the same dependencies, see . Make sure that the prerequisites are met before you try building again. Also, if there are problems, it may be a good idea to first install NGSolve independent of ngsxfem and lateron install ngsxfem separately.
