 The term setRowPrice makes me think of duals.

 However, in OsiCpx, it sends the "rowSol" into argument 6. According to
 the manual, that should be the row solution, i.e., activities (not the
 dual solution). I think you want to use the 8th argument.

 Note - I need a setRowSol method too - which does what is currently done
 in setRowPrice. But, this seems like a bad name or a bug as currently
 implemented.

  int err = CPXcopystart( env_, getMutableLpPtr(), NULL, NULL,
                   const_cast<double*>( colsol_ ),
                   const_cast<double*>( rowsol_ ),
                   NULL, NULL );


 int CPXPUBLIC CPXcopystart(CPXCENVptr env, CPXLPptr lp, const int * cstat,
 const int * rstat, const double * cprim, const double * rprim, const
 double * cdual, const double * rdual)
