Been a while since I have(re)installed a PETSc, but I have just
come into install it as a dependecy for a different package to
that for which I have installed it in the past.
The original package has a requirement for
whereas the current one doesn't, but it does have a requirement for
different external packages, eg hypre.
In terms of laying out PETSc, can (should ?) one use PETSC_DIR
and PETSC_ARCH: to combine everything PETSc-related under one,
with subdirs, or do the differing requirements demand two different "top-level "
hierachies, each then with duplicated files across the two?
Any pointers welcome,
