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 existance 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_CFLAGS)
 AC_SUBST(SQLITE3_LDFLAGS)
 AC_SUBST(SQLITE3_VERSION)

And sets:

 HAVE_SQLITE3
