# Configure paths and flags for the @PACKAGE_PRETTY_NAME@ library.
# Denis Arnaud <denis_arnaud at users dot sourceforge dot net>, July 2008
#
# Note: the @PACKAGE_NAME@ library depends upon BOOST to build.
# Your configure.ac must therefore define appropriately the BOOST
# variables (i.e., BOOST_CFLAGS, BOOST_LIBS, BOOST_DATE_TIME_LIB).
#
# Variables set by this macro:
#  * @PACKAGE_NAME@_VERSION
#  * @PACKAGE_NAME@_CFLAGS
#  * @PACKAGE_NAME@_LIBS
#  * @PACKAGE_NAME@_SAMPLE_DIR
