Short of that changing, the results wouldn't change = either.=20 To build a set of objects you need to worry about at least the = following: - build recipes for each of them (which may also depend on other things) - configuration parameters - dealing with differences on each platform - third party libraries & alternatives - toolchains (& may be cross-platform builds) - supporting/navigating different versions of the last 3 above You can't really precompute all this as there are far too many = combinations and they keep changing.
