[vtkusers] linking problems after upgrade from CMake-2.8.6 to CMake-2.8.12.2

I have an MFC/Vtk  c++ program that I had been building without problems until I upgraded from CMake-2.8.6 to CMake-2.8.12.2   (This is on Windows with Visual Studio 10)

After the CMake upgrade I got link errors indicating:

1>msvcrtd.lib(crtexew.obj) : error LNK2019: unresolved external symbol _WinMain at 16 referenced in function ___tmainCRTStartup
1>C:\Projects\VtkPrograms\VTKPatheter\build\Debug\vtkPatheter.exe : fatal error LNK1120: 1 unresolved externals

I tried a few things to try and resolve this (changing subsystem to CONSOLE or WINDOWS didn't fix it), but couldn't really figure it out.

I rebuilt VTK (v 5.8.0) successfully with the newer version of CMake, but couldn't get my own program to build without the linking problem.

So I gave up and went back to CMake-2.8.6, but I am wondering if anybody ran into this issue and what sort of magic is required in the CMakelist.txt file to fix it.

Thanks for whatever help you can give me
