Generally, the easiest way is to use pkg-config(1) to determine the
necessary flags. Thus, the output of:

	pkg-config --cflags taglib

should be added to $CPPFLAGS in your Makefile(s). Likewise, the output
of:

	pkg-config --libs taglib

should be added to $LIBS

If you're using Autoconf/Automake, one easy way to do this is to use
the PKG_CHECK_MODULES() macro. For example, put:

PKG_CHECK_MODULES(TAGLIB,taglib,[],[AC_MSG_ERROR([*** TagLib not found
***])])

in your 'configure.ac', then add '@TAGLIB_CFLAGS@' and '@TAGLIB_LIBS@'
to 'AM_CPPFLAGS' and '<target-name>_LDADD' respectively in your
'Makefile.am'(s).

Cheers!
