how to find #include files

Hello

I am using ECB 2.32 from debian testing for one of my projects.
Here are the files organisation of this project.

root
|-> include
|	  |->hkl
|	       |->f1.h
|	       |->f2.h
|-> src
      |-> f1.c
      |-> f2.c


when I started ecb with ecb-activate everything went fine and a
lots of buffers appeared.

1 the project files,
2 the files in the selected directory,
3 and analyse window
4 and the history at the left of the emacs edition buffer.

Now my problem is when I use the analyze buffer.
In the Includes node all the .h files are available
when I click on the <stdio.h> file everythings is fine it appears in
the edition buffer but when I click on one of my project .h files
nothing append.

How can I teach ECB where to find my .h files.

Thank you

Frederic
