Last change on this file since 0c74aa was 3b35e7, checked in by Frederik Heber <heber@…>, 11 years ago

Fixes due to update to Ubuntu 14.04.

subdir-objects is default behavior for automake.
INCLUDES is deprecated (in favor of AM_CPPFLAGS), made sure that every .._CPPFLAGS includes AM_CPPFLAGS.
updated boost.m4 (serial 22), re-added missing macros.
qwt.m4 does not use QString in constructor, as it pulls in QtCore dependency.
VectorUnitTest lacked libboost_system dep.

37	# This file provides several macros to use the various Boost libraries.
38	# The first macro is BOOST_REQUIRE. It will simply check if it's possible to
39	# find the Boost headers of a given (optional) minimum version and it will
40	# define BOOST_CPPFLAGS accordingly. It will add an option --with-boost to
41	# your configure so that users can specify non standard locations.
42	# If the user's environment contains BOOST_ROOT and --with-boost was not
43	# specified, --with-boost=$BOOST_ROOT is implicitly used.
44	# For more README and documentation, go to http://github.com/tsuna/boost.m4
45	# Note: THESE MACROS ASSUME THAT YOU USE LIBTOOL. If you don't, don't worry,
46	# simply read the README, it will show you what to do step by step.
