This is probably a good idea.  Please add it to the bug tracker as a
feature request:

  http://www . cmake . org/Bug

There is one minor problem, though.  Visual Studio 6 does not
detect/reload a .dsw file when it changes as it does for .dsp files.  If
re-running cmake on the whole project through this link causes a library
to be added or a dependency between .dsp files to change, that information
will not be reloaded until you manually close the project and re-open it.
