[vtkusers] /MD(d) vs /MT(d)

[Goodwin Lawlor]

Hi Erik,

You're right - CMake could be improved to make handling the C runtime libs
a little easier. They need to be edited manually in multiple places in the
CMake gui usually.

Your case wouldn't hold for all people though - you can build static VTK
libs against shared C runtimes if you need to.

I'd like to see a "Use Static C Runtime Libraries" option in CMake that
adds /MT(d) to the linker options instead of /MD(d) by default.

Thanks,

Goodwin
