[CMake] cmake and wxwidgets on windows

[Werner Smekal]

Hi John,

now please run 

make VERBOSE=1

and send the output to the list. Then we exactly see how cmake calls the
compiler, which version of wxWidgets is used and which macros get
defined at the command line. As Vadim wrote on the wxWidgets mailing
list, this is very likely a mixup of unicode with non-unicode code.

Regards,
Werner
