When using pkg-config, the harfbuzz paths are included in the output:

# pkg-config --cflags pango
-I/usr/pkg/include/pango-1.0 -I/usr/pkg/include -I/usr/pkg/include/glib-2.0 -I/usr/pkg/lib/glib-2.0/include -I/usr/pkg/include/harfbuzz -I/usr/pkg/include/fribidi -I/usr/X11R7/include/freetype2 -I/usr/pkg/include/uuid -I/usr/X11R7/include -I/usr/pkg/include/cairo -I/usr/X11R7/include/pixman-1 -I/usr/pkg/include/libpng16 -D_REENTRANT

So this should already work correctly. Can you please check why this
doesn't work in your setup?
