# 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 installation 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
