[Insight-developers] Update CMake build (Replace Unsupported with Auxiliary)

[Will Schroeder]

Hi Folks-

Last Friday I changed Unsupported to Auxiliary. I forgot to modify the CMakeLists.txt file. I have now done so, and replaced the BUILD_UNSUPPORTED with BUILD_AUXILIARY. You'll want to delete the BUILD_UNSUPPORTED CMake cache entry. (On Windows you can right click and select delete. I think this is true as well for the FLTK version. If you are using the Unix Curses (ccmake) version, you type a "d" over the cache entry.)
