How to determine the main version of a shared library in autoconf?

I use autoconf / automake / libtool to create a shared library. I want to transfer a large number of library versions for library sharing.

I have the following declaration in the configure.ac file:

AC_INIT([libabc], [1.1.0])

And the following Makefile.am:

AM_CPPFLAGS              = -I$(top_srcdir)/include -Wall -Wextra
LDADD                    = libabc.la

lib_LTLIBRARIES          = libabc.la
nodist_libabc_la_SOURCES = $(top_srcdir)/config.h
libabc_la_SOURCES        = $(top_srcdir)/src/abc.c

I am fine to have the same version for the configuration of the script, sources and sonata for the shared library. I can use VERSION or PACKAGE_VERSION defined in auto-generated config.h in the sources, but this does not affect soname, which is always libabc.so.0.

Is there a way to force libtool to use my main version from the AC_INIT directive? If not, what is the preferred way to determine the primary / minor number?
