dnl AM_PATH_KSBA([MINIMUM-VERSION,
dnl [ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND ]]])
dnl Test for libksba and define KSBA_CFLAGS and KSBA_LIBS
dnl MINIMUN-VERSION is a string with the version number optionalliy prefixed
dnl with the API version to also check the API compatibility. Example:
dnl a MINIMUN-VERSION of 1:1.0.7 won't pass the test unless the installed
dnl version of libksba is at least 1.0.7 *and* the API number is 1. Using
dnl this features allows to prevent build against newer versions of libksba
dnl with a changed API.
