This is kind of a mess, but basically: - static=true, shared=true means to build statically but move it to the static output - static=true, shared=false means to build statically and leave it in the main output - static=false, shared=true means to not build static at all Confusingly, the old default was static=true, shared=true even though static=false? Still can’t figure out what was meant by that.
