+# "core" libs first, then others alphebetically as far as possible
+# NOTE: for speed of meson runs, the dependencies in the subdirectories
+# sometimes skip deps that would be implied by others, e.g. if mempool is
+# given as a dep, no need to mention ring. This is especially true for the
+# core libs which are widely reused, so their deps are kept to a minimum.
