cmake $builddir

does exactly that. The ZERO_CHECK visual studio target that is present in every cmake generated solution does this: it checks if cmake needs to be re-run. It is built before every other target. So your batch file does a lot of things that are already done by cmake.

Well unless you explicitly disabled this. But you'd know then.
