I cannot use wx-config when I don't have wxWidgets installed because it 
doesn't exists. Only after wxWidgets is built I can use wx-config to extract 
compiler and linker flags, that's the problem. When it is preinstalled, it's 
a snap, find_package(wxWidgets) does the trick.

FindwxWidgets actually does this parsing, while UsewxWidgets.cmake assigns 
the variables to cmake's variables, you shouldn't have to do it by hand.
