#define GTK_THEME_DIR "@GTK_THEME_DIR@/gtk-2.0"
#define OXYGEN_DEBUG @OXYGEN_DEBUG@
#define OXYGEN_ICON_HACK @OXYGEN_ICON_HACK@

```

Make it possible to easily override OXYGEN_DEBUG in any cpp file
user
```cmake
#ifndef __CONFIG_H__
#define __CONFIG_H__

#define GTK_THEME_DIR "@GTK_THEME_DIR@/gtk-2.0"
#ifndef OXYGEN_DEBUG
