PETSc.jl with system petsc?

[jkozdon]

I couldn't tell, but it seems that you cannot use a system installed PETSc with this. Is that correct?

Actually, with Julia 1.6 I cannot even get it to work with the binary

blowing away my .julia worked. I think I was using MPI.jl with OpenMPI_jll and PETSc_jll uses MPICH_jll
