\subsection{Using GNU autoconf}\label{group__building_autoconf}
If you are using GNU autoconf, you do not need to call pkg-config directly. Use the following macro to determine if liboggz is available:

\small\begin{alltt}
 PKG\_CHECK\_MODULES(OGGZ, oggz >= 0.6.0,
                   HAVE\_OGGZ="yes", HAVE\_OGGZ="no")
 if test "x$HAVE\_OGGZ" = "xyes" ; then
   AC\_SUBST(OGGZ\_CFLAGS)
   AC\_SUBST(OGGZ\_LIBS)
 fi
 \end{alltt}
\normalsize 


If liboggz is found, HAVE\_\-OGGZ will be set to \char`\"{}yes\char`\"{}, and the autoconf variables OGGZ\_\-CFLAGS and OGGZ\_\-LIBS will be set appropriately.\subsection{Determining compiler options with pkg-config}\label{group__building_pkg-config}
If you are not using GNU autoconf in your project, you can use the pkg-config tool directly to determine the correct compiler options.

\small\begin{alltt}
 OGGZ\_CFLAGS=`pkg-config --cflags oggz`\end{alltt}
\normalsize 


\small\begin{alltt} OGGZ\_LIBS=`pkg-config --libs oggz`
 \end{alltt}
\normalsize
