# - we deliberately list libdarshan-mpi-io twice in the link command.  The
#   first is necessary to correctly use the MPI profiling interface.  The
#   final one is necessary to give the linker a change to resolve indirect
#   dependencies on PnetCDF and HDF5 symbols (if the app used a library which 
#   in turn used one of those HLLs).
