One thought I had here was to have the "vcbuild" command clean any affected projects. This would have the advantage of isolating CMake from implementing any Visual Studio specific mods (i.e. delete these object files to force a recompilation, etc.). This would have some downsides though. 1. The easiest implementation would just be to perform the clean if a project file changes. This would result in more cleaning then necessary as changing source files (for example) shouldn't cause a rebuild. Certain project modifications like adding a source file to a target shouldn't cause a clean of that target. 2. Perhaps the biggest gotcha of all, "cleaning" a target would wipe out any binaries/libraries already generated. This is far different from the behavior of CMake's Makefile generator which simply causes targets to be rebuilt on the next "make". Anyone have any ideas for fixing this? I've been bit by this one before (forgetting to rebuild everything when I change a preprocessor definition at the global scope). -- Philip Lowman
