#
# SYNOPSIS
#
# AX_LIB_NOKALVA([ACTION-IF-TRUE], [ACTION-IF-FALSE])
#
# DESCRIPTION
#
# This macro will check for the existence of OSS Nokalva
# (http://www.oss.com/products/). It does this by checking for the header
# file asn1.h and the cppsoed library object file. A --with-nokalva option
# is supported as well. The following output variables are set with
# AC_SUBST:
#
# NOKALVA_CPPFLAGS
# NOKALVA_LDFLAGS
# NOKALVA_LIBS
#
# You can use them like this in Makefile.am:
#
# AM_CPPFLAGS = $(NOKALVA_CPPFLAGS)
# AM_LDFLAGS = $(NOKALVA_LDFLAGS)
# program_LDADD = $(NOKALVA_LIBS)
#
# Additionally, the C preprocessor symbol HAVE_NOKALVA will be defined
# with AC_DEFINE if Nokalva is available.
