John,

I don't think the following setting is appropriate for your platform:

SET(CMAKE_FIND_LIBRARY_PREFIXES "")
SET(CMAKE_FIND_LIBRARY_SUFFIXES ".lib")

Also, the following line is deprecated:

SET(wxWidgets_USE_LIBS base core gl net)

you should rather use:

FIND_PACKAGE(wxWidgets REQUIRED base core gl net)

Now, if you want help debugging your problem, you need to stay on
track and provide the information necessary for me to determine what
might be the problem. After reviewing the output from the uncommented
debug macros, I asked you for the directory dump so that I can see
what is there and why it is not finding base and core. Please send
that information.

If there is a bug in the FindwxWidgets module, I will apply a patch to solve it.
