Not much success. I tried running CMake naively and was instantly 
greeted with the recommendation to run cmake/configure. Which of course 
is a shell script so needs to be run from Cygwin. When I do that (after 
some fiddling with --src and --generator) it complains that the win32 
directory doesn't have a CMakeLists.txt:

$ ../platforms/win32/cmake/configure --src=./src/ --generator="Visual 
Studio 10"
-- Configuring squeak  for i686-pc-cygwin
-- Using source directory /cygdrive/c/SqueakVM/cmake-test/winbuild/src
-- Using generator Visual Studio 10
../platforms/win32 -DVM_HOST=i686-pc-cygwin -DPLATFORM_SOURCE_VERSION= 
-DVM_VERSION= -DOPT--src=/cygdrive/c/SqueakVM/cmake-test/winbuild/src
CMake Error: The source directory 
"C:/SqueakVM/cmake-test/platforms/win32" does not appear to contain 
CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Which is correct, but I don't see a CMakeLists.txt in the patches. So 
I'm at a loss at this point. Geoffrey, any instructions?

I think the benefit for me would be elsewhere, namely in being able to 
just gen Makefiles for various compiler versions. It is quite a pain in 
the rear to try to load a Visual Studio X build file into a Visual 
Studio X-1; if cmake could make address this it might be worthwhile for 
that reason alone.

That's okay, I'm just trying to see what cmake actually spits out. 
Unfortunately I'm a complete noob in this area so I'm stuck with the above.
