[petsc-dev] [petsc-users] Is it possible to add KLU to petsc as external solver package?

[Barry Smith]

  I think it is likely find to change umfpack.py to suitesparse.py and have only a --download-suitesparse 

  I don't think it is worth our while to try to manage various downloads of parts of it as well as the whole thing.

I never implemented --download-cholmod because it's more difficult to install than building all of SuiteSparse. Would it be reasonable for the --download stuff to always build all of SuiteSparse? We can still support linking to the user-provided umfpack/cholmod/amd independently from all of SuiteSparse.
