Some might think, myself included, that some of the problems you are stating is caused by build system dogma, e.g. "stop building build systems, other projects aren't moving, so it makes you esoteric". Current build systems suck. It also sucks that there are so many. It's unfair that everyone has to hear that they contribute to the latter just because they want to solve the former. What sucks more to me than finding a lib using its own build system is finding a lib that won't adopt more modern ones or languages that refuse to fix their defacto language-specific build systems, both caused by the sentiments you state about having too many and/or it being too hard for builders to change their ways. There is a middle ground here and it starts with asking software to move forward, not asking it to stop.
