[CMake] Finding MinGW compiler libraries?

MinGW is installed in standard fashion.  Nothing unusual there.
No environment variables, like LIB etc., are set that might cause
problems.

To me that seems counter to the whole reason to use CMake
in the first place.  I could have just written Makefile to do that.

This is where I'm coming from.  I wrote a XML parser
to deal with Atmel configuration files on Linux.
I wanted it to be cross platform.  I knew that
the autotools would be a problem to make a Windows
version, so I thought I'd give CMake a try,
even bought your book.  Everything worked just great
on Linux, no problems at all.  Quickly had a working
program.

However as chronicled in a couple of threads here
I've found using CMake with MinGW in conjunction
with wxWidgets to be a nightmare.  I've spent
days trying to get things to link, and still
don't have a working program.  I know many
of the issue have been self inflicted as I learn
CMake.  I expected everything to 'just work'
the way it did under Linux.  Apparently
my expectation was to optimistic,
after all this is Windows.

Perhaps if someone could point me to a working example
of MinGW (Not MSYS)/wxWidgets/CMake would help?

Miguel has been especially patient with me, both on and off the
list here, in getting my CMake/MinGW/wxWidgets issues sorted out,
and I want to publicly thank him for all of his help.
