#define MATSOLVERSPQR            "spqr"

For example: “petsc” indicates what PETSc provides, “superlu_dist” the parallel SuperLU_DIST package etc

Note

MATSOLVERUMFPACK, MATSOLVERCHOLMOD, MATSOLVERKLU, MATSOLVERSPQR form the SuiteSparse package; you can use --download-suitesparse as a ./configure option to install them
