I've been using the following code for libapt-pkg:
AC_LANG_CPLUSPLUS
AC_CHECK_HEADER(apt-pkg/init.h,,
AC_MSG_ERROR([*** You need libapt-pkg]))
AC_CACHE_CHECK([for libapt-pkg],ac_cv_have_libapt_pkg,[
ac_save_LIBS=$LIBS
LIBS=-lapt-pkg
AC_TRY_LINK(
[#include <apt-pkg/init.h>],
[(void)pkgInitialize(*new Configuration())],
[ac_cv_have_libapt_pkg=yes],
[
ac_cv_have_libapt_pkg=no
AC_MSG_ERROR([*** You need libapt-pkg])])
LIBS="$ac_save_LIBS"])
# since we weren't here if the test failed, we can assume HAVE_LIBAPT_PKG
APTPKGLIBS="-lapt-pkg"
AC_SUBST(APTPKGLIBS)
