[vtkusers] VS 2010 64-bit build problems

[Fahlgren, Eric]

I diffed the CMakeCache.txt files between my 32- and 64-bit builds, and noted that the explicit templates flag was 0 in the 64.  I changed it to 1, and what do you know?  Builds fine now without any code changes.

VTK_EXPLICIT_TEMPLATES:INTERNAL=1

This flag is not exposed in the CMake gui, so I have no idea how it got set incorrectly.  Anyone got an explanation?
