##### http://autoconf-archive.cryp.to/ax_lib_sqlite3.html
#
# SYNOPSIS
#
# AX_LIB_SQLITE3([MINIMUM-VERSION],[DEFAULT])
#
# DESCRIPTION
#
# Test for the SQLite 3 library of a particular version (or newer)
#
# This macro takes only one optional argument, required version of
# SQLite 3 library. If required version is not passed, 3.0.0 is used
# in the test of existence of SQLite 3.
#
# If no intallation prefix to the installed SQLite library is given
# the macro searches under /usr, /usr/local, and /opt.
#
# This macro calls:
#
# AC_SUBST(SQLITE3_CPPFLAGS)
# AC_SUBST(SQLITE3_LDFLAGS)
# AC_SUBST(SQLITE3_LIBS)
# AC_SUBST(SQLITE3_VERSION)
#
# And sets:
#
# HAVE_SQLITE3
