Get CFLAGS for a Package with pkg-config

As I tried to cross-compile an application that required glibconfig.h, I found a way to retrieve the CFLAGS for a given package.

Here’s the output for glib-2.0 and gtk-2.0 in qemu for overo:

pkg-config –cflags glib-2.0
-I/usr/include/glib-2.0 -I/usr/lib/arm-linux-gnueabi/glib-2.0/include

pkg-config –cflags gdk-2.0
-pthread -I/usr/include/gio-unix-2.0/ -I/usr/include/pango-1.0 -I/usr/include/glib-2.0 -I/usr/lib/arm-linux-gnueabi/glib-2.0/include -I/usr/include/freetype2 -I/usr/include/libpng12 -I/usr/include/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/include/cairo -I/usr/include/gdk-pixbuf-2.0 -I/usr/include/pixman-1

Finally, I found out that glibconfig,h was in /usr/lib/arm-linux-gnueabi/glib-2.0/include as this file is generated by configure and is platform dependent.
