[CMake] MinGW and Cmake

[Todd Gable]

I've been using Cmake with .Net for ITK/VTK for a little bit now, but I wanted to try gcc/g++ instead. I have MinGW installed (on WinXP)  and working, but Cmake does not see it, at least it's not listed in the drop down box "Build For". I put the gcc bin directory in the Path, is there another step I'm missing, like editing a Cmake config? Sorry if this has been answered before, but my searches were fruitless.
