from an installed tree or a version controlled tree. Determine

Build Visual Studio Projects. We use a template here to instantiate

explicit rules rather than using an implicit rule because we want to

leverage make's VPATH searching rather than specifying the paths on

each file in ALL_EXAMPLES. This has the unfortunate side effect that

touching the source files trigger a rebuild of the project files

even though there is no real dependency there (the dependency is on

the makefiles). We may want to revisit this.
