[vtk-developers] Strange CMAKE_BUILD_TYPE

That is strange.  It should only give "Debug" or "Release" by default, not
both.

This is because all the configurations are generated for MSVC 6 and 7.
Which one is built is selected by the user from the Visual Studio GUI.

One must use the same C++ compiler for two C++ projects that will link
together..  If you build VTK with MSVC, you must use it for the other
project also, and you must select the same build configuration in the
Visual Studio GUI.  If you build VTK with borland, then its
CMAKE_BUILD_TYPE setting must also be used for the other project (if you
are on windows), so it is automatically imported.

This setting is specific to each cmake generator (any Makefile generator
has it, but not the project file generators).  It has nothing to do with
VTK in particular.
