<code>AX_LIB_SQLITE3([MINIMUM-VERSION])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Test for the SQLite 3 library of a particular version (or newer)
</p>
<p>
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.
</p>
<p>
If no intallation prefix to the installed SQLite library is given the macro
searches under /usr, /usr/local, and /opt.
</p>
<p>
This macro calls:
</p>
<pre>
AC_SUBST(SQLITE3_CFLAGS)
AC_SUBST(SQLITE3_LDFLAGS)
AC_SUBST(SQLITE3_VERSION)
</pre>
<p>
And sets:
</p>
<pre>
HAVE_SQLITE3
</pre>
