<h2>
Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>AC_PATH_GENERIC(LIBRARY [, MINIMUM-VERSION [, ACTION-IF-FOUND [,
ACTION-IF-NOT-FOUND]]])</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Runs a LIBRARY-config script and defines LIBRARY_CFLAGS and LIBRARY_LIBS
</p>
<p>
The script must support `--cflags' and `--libs' args. If MINIMUM-VERSION is
specified, the script must also support the `--version' arg. If the
`--with-library-[exec-]prefix' arguments to ./configure are given, it must
also support `--prefix' and `--exec-prefix'. (In other words, it must be
like gtk-config.)
</p>
<p>
For example:
</p>
<pre>
AC_PATH_GENERIC(Foo, 1.0.0)
</pre>
<p>
would run `foo-config --version' and check that it is at least 1.0.0
</p>
<p>
If so, the following would then be defined:
</p>
<pre>
FOO_CFLAGS to `foo-config --cflags`
FOO_LIBS to `foo-config --libs`
</pre>
<p>
At present there is no support for additional "MODULES" (see AM_PATH_GTK)
(shamelessly stolen from gtk.m4 and then hacked around a fair amount)
