[CMake] copying directory structure : path issue

[Benoit Callebaut]

Hello,
I need to copy a directory structure into a MAC OSX bundle at build  
time and to generate a configuration file containing the file-paths of  
those file (or at least the directories where they are located).

I can up to now copy the files in the bundle but CMAKE destroys the  
directory structure.

I looked for options and even using REGEX to strip the path (without  
an success).

How can I do it ?

Thanks,

Benoit
