[CMake] How to create a 64-bit Windows build of cmake? Added for building vtk-5.0.0

To close out this thread, I think I can now explain what was
happening.

I was indeed getting a win64-release version of cmake, by
configuring in a Visual Studio Win64 command window with

cmake \
   -G 'NMake Makefiles'
   -DCMAKE_INSTALL_PREFIX:PATH=C:/winsame/contrib-vs9/cmake-2.8.5-ser \
   -DCMAKE_BUILD_TYPE:STRING=RELEASE \
   -DCMAKE_C_COMPILER:FILEPATH='cl' \
   -DCMAKE_CXX_COMPILER:FILEPATH='cl'
<path to source>

then doing "nmake; nmake package" and using that package
to install cmake.  This only problem was that the default
location came out as /Program Files/... instead of /Program
Files (x86)/..., but this was modified at installation time.

But then in configuring VTK, CMake was constructing the
libraries, such as cmVTK_WRAP_TCL2.dll, as Debug.  The problem
was that the flag, -DCMAKE_BUILD_TYPE:STRING=RELEASE,
was not getting used by the TRY_COMPILE in
CMake/vtkCompileCMakeExtensions.cmake to configure
CMake/CMakeLists.txt.

CMake/vtkCompileCMakeExtensions.cmake, which is used by the
configuration of CMake/CMakeLists.txt.  So now I send this
explicitly as shown in the patch below.  All now configures
and builds.

So should CMake pass the flag, CMAKE_BUILD_TYPE, automatically
to try_compile?  Or should the module do that?  (It would seem
that CMake would have to send its build type to the module if
it were to load it, but it would have to respect the build type
if a built application were to load it.)  Because I my
uncertainty, do not know whether to report this as a bug.

Thx......John Cary
