[CMake] Why does cmake adds /STACK:10000000 for msvc linker?

[Andrew Maclean]

I think the reason was that when Visual Studio 6 was used to build VTK
it used to run out of stack space necessitating the large value that
needed to be set.

I am pretty sure that this was the case because I think I was one of
the people who noted this problem in the "old days"!
