By default, IpoptSolver uses MUMPS to solve the linear program. Users can now set the solver option "linear_solver" to "spral" to use SPRAL instead. Add new build dependencies to the workspace: - Add gklib_internal - Add metis_internal - Add spral_internal Run ipopt_solver_test with both linear solvers. Adjust license checker to allow british spelling.
