# ===========================================================================# https://www.gnu.org/software/autoconf-archive/ax_boost_thread.html# ===========================================================================## SYNOPSIS## AX_BOOST_THREAD## DESCRIPTION## Test for Thread 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_THREAD_LIB)## And sets:## HAVE_BOOST_THREAD## LICENSE## Copyright (c) 2009 Thomas Porschberg <thomas@randspringer.de># Copyright (c) 2009 Michael Tindal## 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.
