#985: add OPTIONAL dependency on MPI to HDF5 -----------------------------------+---------------------------------------- Reporter: rhaas | Owner: Type: defect | Status: new Priority: minor | Milestone: Component: EinsteinToolkit thorn | Version: Keywords: HDF5 | -----------------------------------+---------------------------------------- With #980 thorns using a compiled HDF5 version that has parallel MPI enabled (such as the the one on my debian system which I need because either PetSC or libsiloh5 wanted it) do not compile anymore. Adding {{{ OPTIONAL HDF5 { } }}} to ExternalLibraries/HDF5's confguration.ccl fixes this. Ok to apply?
