	Hum, I guess I was not clear.

	I built wxWindows DLL properly but for WIN32 you need to define a 
special tag for each symbol you want to export in your DLL. And for that 
to work, wxWindow assume you pass 'DLLUSINGDLL' to the preprocessor (it 
will have consequence on included wx files).

	What I suggest is (*):

	Jan what do you think of it ? Can anybody from cmake-dev-team answer on 
this ? I tried looking at FindQT, and this was the way used for passing 
QT_DLL (~WXUSINGDLL) when linking against Qt's DLL. Then all you have to 
do in your *own* CMakeLists.txt is to add:

	ADD_DEFINITIONS(${WXWINDOWS_DEFINITIONS})

Thanks
