# ===========================================================================#     https://www.gnu.org/software/autoconf-archive/ax_boost_process.html# ===========================================================================## SYNOPSIS##   AX_BOOST_PROCESS## DESCRIPTION##   Test for Process library from the Boost C++ libraries. The macro#   requires a preceding call to AX_BOOST_BASE. Further documentation is#   available at <http://randspringer.de/boost/index.html>.##   This macro calls:##     AC_SUBST(BOOST_PROCESS_LIB)##   And sets:##     HAVE_BOOST_PROCESS## LICENSE##   Copyright (c) 2008 Thomas Porschberg <thomas@randspringer.de>#   Copyright (c) 2008 Michael Tindal#   Copyright (c) 2008 Daniel Casimiro <dan.casimiro@gmail.com>##   Copying and distribution of this file, with or without modification, are#   permitted in any medium without royalty provided the copyright notice#   and this notice are preserved.
