Note that (since Meson 0.57.0) you can set optimization to, say, 2 in your debug builds if you want to. If you tried to set this flag based on optimization level, it would fail in this case. + +## How do I use a library before declaring it? + +This is valid (and good) code: +``` +libA = library('libA', 'fileA.cpp', link_with : []) +libB = library('libB', 'fileB.cpp', link_with : [libA]) +``` +But there is currently no way to get something like this to work: +``` +libB = library('libB', 'fileB.cpp', link_with : [libA]) +libA = library('libA', 'fileA.cpp', link_with : []) +``` +This means that you HAVE to write your `library(...)` calls in the order that the +dependencies flow.
