`man pkg-config`, try "pkg-config --cflags gnome-vfs-2.0". 

You should add a pkg-config check to your configure script.

To do it you must add it to your configure.in or configure.ac and then
run autoconf to commit the changes.
 
Open your configure.in (or *.ac) and add this lines:


echo -n "checking for gnome-vfs-2.0... "
if pkg-config --exists gnome-vfs-2.0 ; then
        echo "ok"
        VFSFLAGS=`pkg-config --cflags gnome-vfs-2.0`
        VFSLIBS=`pkg-config --libs gnome-vfs-2.0`
        CFLAGS="$CFLAGS $VFSFLAGS"
        LIBS="$LIBS $VFSLIBS"
else
        echo "failure"
        AC_MSG_ERROR(gnome-vfs-2.0 not found please install the gnome
development package)
fi


I'm supossing you use CFLAGS and not PKG_CFLAGS or other variable names
to hold the compiler flags, and you use LIBS and not PKG_LIBS to hold
linker flags.

If your configure.[in|ac] have the line:

PKG_CHECK_MODULES(PACKAGE, [$pkg_modules])

You can then use the following code - copy it before the
PKG_CHECK_MODULES line.

echo -n "checking for gnome-vfs-2.0... "
if pkg-config --exists gnome-vfs-2.0 ; then
        echo "yes"
        pkg_modules="$pkg_modules gnome-vfs-2.0"
else
        echo "no"
        AC_MSG_ERROR(gnome-vfs-2.0 not found please install the gnome
development package)
fi

Remember to run autoconf after the changes to let autotools convert your
configure.[in|ac] to a "configure" script, and then run configure itself
to commit the changes to the Makefiles.
