# OMPI_CHECK_UGNI(prefix, [action-if-found], [action-if-not-found])
# --------------------------------------------------------
# check if GNI support can be found. sets prefix_{CPPFLAGS,
# LDFLAGS, LIBS} as needed and runs action-if-found if there is
# support, otherwise executes action-if-not-found
#
# NOTES
# on Cray XE6 systems, the GNI development header (gni_pub.h) is in a
# completely different place than the ugni library (libugni).
#
# EXAMPLE CONFIGURE USAGE:
# --with-ugni=/base/path/to/libugni --with-ugni-includedir=/path/to/gni_pub.h
#
# --with-ugni=/opt/cray/ugni/default --with-ugni-includedir=/opt/cray/gni-headers/default/include
