#------------------------- mpi wrappers -----------------------
# Build libmpiwrap.so for the primary target only.
#
# This is really horrible.
#
# Don't let automake install this, since it puts it in the
# wrong place. Instead install it ourselves in the right
# place using the install-exec-local target below.
#
# Also, automake isn't good at supporting non-$(CC) compilers.
# But we need to use $(MPI_CC) here. Hence the nasty hack of
# directly saying how to build libmpiwrap.so, instead of
# using automake's standard gunk.
