More CMake work:

- various fixes for using CMake on Windows
- support building external SDL, zlib, CLRun, wxWidgets
- support using precompiled GLew and WiiUse libs on Windows

For what it's worth, I'm not quite sure if I got all the wx files right...
Building with MSVC2008 still doesn't work yet, but is a lot closer now.
