Does CMake delete the generated extra_targets.vcproj when you rerun
cmake with -DBUILD_EXTRA_TARGETS=OFF? I would not be surprised if the
.vcproj are left lying around.

Perhaps VS is smart enough to notice when new files appear but not when
existing files disappear?

I tend to close/reopen VS when making CMake changes anyway because the
reload macros are quite unreliable for me.
