[vtkusers] How to FindVTK libraries with debug suffix

[Kenneth Porter]

I'm building VTK debug libraries with a "_d" suffix so that I can have both 
release and debug versions readily available when building my apps. But 
when building an example app using a CMakeLists.txt file, I find I need to 
edit the resulting Visual Studio 2008 project file to add the debug suffix 
to the library references, or the app crashes because it's using the wrong 
libraries.

It looks like CMake is getting the ability to locate libraries with debug 
suffixes:

<http://www.cmake.org/pipermail/cmake/2010-February/035055.html>

What would be involved in adding this to the VTK build machinery?

For reference, here's how I'm currently building VTK:

Unpack VTK to g:\devel\vtk\vtk-5.4.2.

cd g:\devel\vtk\output\vs9
cmake -D CMAKE_DEBUG_POSTFIX="_d" -D CMAKE_INSTALL_PREFIX=G:/devel/VTK/vs9 
-D VTK_DEBUG_LEAKS=ON -G "Visual Studio 9 2008" ..\..\vtk-5.4.2
@rem build debug and release versions with VS2008

cd g:\devel\vtk\output\vs8
cmake -D CMAKE_DEBUG_POSTFIX="_d" -D CMAKE_INSTALL_PREFIX=G:/devel/VTK/vs8 
-D VTK_DEBUG_LEAKS=ON -G "Visual Studio 8 2005" ..\..\vtk-5.4.2
@rem build debug and release versions with VS2005

To build an example from the wiki, I copy the files from the wiki to 
g:\devel\appname\src, cd to g:\devel\appname\bin, and run:

cmake -D CMAKE_DEBUG_POSTFIX="_d" -D VTK_DEBUG_LEAKS=ON -D 
VTK_DIR="g:/devel/VTK/vs9/lib/vtk-5.4" -G "Visual Studio 9 2008" ../src
