# m4 configure test script for the SoundTouch library
|
|
#
|
|
# This file can be included with other packages that need to test
|
|
# for libSoundTouch.
|
|
#
|
|
# It will #define HAVE_LIBSOUNDTOUCH iff the library is found
|
|
# It will AC_SUBST SOUNDTOUCH_LIBS and SOUNDTOUCH_CXXFLAGS as well
|
|
# It also defines some flags to the configure script for specifying
|
|
# the location to search for libSoundTouch
|
|
#
|
|
# A user of libSoundTouch should add @SOUNDTOUCH_LIBS@ and
|
|
# @SOUNDTOUCH_CXXFLAGS@ to the appropriate variables in his
|
|
# Makefile.am files
|
|
#
|
|
# This script works with autoconf-2.5x and automake-1.6 but I have
|
|
# not tested it with older versions.
