[CMake] configuration of VTK 5.8 using cmake 2.6 on 64-bit windows 7

[rakesh patil]

Hello,

I want to compile VTK 5.8 for 64bit windows machine. I have cmake 2.6 for
32-bit windows. I downloaded vtk source code from www.vtk.org website.
While configuring, I select Visual Studio 9(64) and continued
configuration. Then I made following changes

CMAKE_CXX_FLAGS = /D_WIN64 /D_WINDOWS (Default was /DWIN32 /D_WINDOWS)
CMAKE_C_FLAGS = /D_WIN64 /D_WINDOWS (Default was /DWIN32 /D_WINDOWS)
CMAKE_INSTALL_PREFIX = Appropriate path where lib, header and dll files will
be saved
VTK_DATA_ROOT = Path where vtk data resides.

Now what i want to ask is that
1) Is it perfectly fine to use 32-bit version of cmake to compile 64bit
version of VTK?
2) What effect will it be if WIN32 is replaced with _WIN64 in flags above?

Thanks

Regards
Rakesh Patil
