[CMake] How to find wxWidgets with cmake under Windows?

Yes, sorry.  Was feeling frustrated that something that I thought was going
to be simple wasn't.

Normally I don't either.  I only did it because it wasn't being found with
the WXWIN environment variable.   I usually just unzip because I frequently
build with different versions.

This is all I'm finding:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\wxWidgets_is1

wxWidgets_CONFIG_EXECUTABLE-NOTFOUND
wxWidgets_wxrc_EXECUTABLE-NOTFOUND

are the only two wxWidgets I see in 
C:\program files\cmake 2.6\bin\cmake-gui.exe 
even with 'show advanced settings' set.

Where should I be seeing wxWidgets_ROOT_DIR?

Why did WXWIN not locate it?

Did that. Still doesn't find it.  :-(

I know it is at c:\wxWidgets-2.8.8 and works because I ran some of the sample 
programs after building it.

You have C:/wxW... above where I have C:\wxW...  does the direction of the
slash make a difference here?
