[UNIX] Build error

[Gildas Fargeas]

Hi,
I get an error message when I try to build wxArt on my machine.

/[wxArt2D_BUILD]$ cmake --debug-output ../wxArt2D
Running with debug output on.
CMake Error: Error in cmake code at

/I've seen that somebody had this same error but there are not 
sufficient replies to solve the problem...
I use wxWidgets 2.6.4 with GTK2 port and unicode enabled.
I've ccmake the program in order to have it match my wxwidget config.

I have absolutely no idea of where it could be from!! So, thank you for 
your help.
