# OMPI_INSTALL_DIRS(header_file)
# ------------------------------
# Write out the installation directories into a header file that is
# written by AC_SUBST so that files that depend on hard-coded paths
# can include it and be rebuilt when paths change. We don't AC_DEFINE
# because we don't want to rebuild the entire tree just because
# someone changed the prefix.

# be done later so that NONE doesn't show up in the
# exec_prefix-based variables. We don't use '${prefix}' because
# we don't want to have to double evaluate those variables.
