# Example op component configure.m4 file.  This file is slurped in by
# Open MPI's autogen.pl to be part of the top-level configure script.
# This script must define (via AC_DEFUN) an m4 macro named
# MCA_<framework>_<component>_CONFIG that executes either $1 if the
# component wants to build itself, or $2 if the component does not
# want to build itself.

# Do *NOT* invoke AC_MSG_ERROR, or any other macro that will abort
# configure, except upon catastrophic error.  For example, it *is* a
# catastropic error if the user specifically requested your component
# but it cannot be built.  If it *not* a catastropic error if your
# component cannot be built (but was not specifically requested).

# See https://github.com/open-mpi/ompi/wiki/devel-CreateComponent
# for more details on how to make Open MPI components.
