atk/atkobject.h: No such file or ...

["Jamiil Abduqadir" <jalqadir gmail com>]

OK folks, here is one I just don't get. I am really confused about this.
Here I go, I have just installed gtkmm version 2.10  from 

http://ftp.gnome.org/pub/gnome/binaries/win32/gtkmm/
After the installation I tested the installation with a simple "hello" program, 

it compiled and ran without any problems. After that, it was work time and 

started porting an existing class to gtkmm. Changing variables from 'std' to 

'Glib' or to 'Gtk' was no problem, but then I added a button and a signal with 

its corresponding method, since then I get the below message.

what is confusing to me is the that, according to the message, 'atkobject.h' is 

not found under the '../atk/' folder, but I found it in the folder 

'D:/XWin/include/atk-1.0/atk/', so, what is causing the problem.

Thanks in advance folks
