Oops - missed replying to the list.  Visual Studio 2010.  I can try to
create a small test case, but in the mean time we can avoid the issue
by setting CMAKE_SUPPRESS_REGENERATION to ON for Visual Studio
generators only.  As long as Visual Studio can't cleanly handle
re-loading everything quietly after a CMake re-run, there's no point
in allowing regeneration from Visual Studio at all.  Perhaps an
alternative would be to print a warning that the CMakeCache.txt file
looks newer than the generated build system - is there anything in
CMake that can provide that capability?

Thanks,
Cliff
