That technique is somewhat old school. The more modern way to do
things is with the pkg-config tool.

For something called whatever, it might look like:

PKG_CHECK_MODULES(WHATEVER, whatever >= 1.0.6, ac_cv_whatever=1, 
ac_cv_whatever=0)
AC_DEFINE_UNQUOTED([HAVE_WHATEVER],$ac_cv_whatever,[Set to 1 if you have 
libwhatever.])

In your Makefile.am you can then use @WHATEVER_CFLAGS@ and @address@hidden

HTH,
