Great PR overall. The only thing that I'd change/improve is the naming "MINIMUM_BUILD - BUILD_WITH_ALL". To me, "BUILD_WITH_ALL" sounds rather non-intuitive and not self-explanatory (Build with all the =what=?) Secondly, the pair "MINIMUM_BUILD - BUILD_WITH_ALL" is non-symmetric morphologically. Thirdly, I would stick to underscore-free flag convention as it reduces guessing whether words are separated or not. The naming natural to me would be "MINBUILD - MAXBUILD" or "NOEXTRAS - ALLEXTRAS" or so, but it's only my subjective suggestion.
