+# * libelf isn't strictly necessary, but makes gresource tool more useful, and
+# the check is automagic in gio/meson.build. gresource is not a multilib tool
+# right now, thus it doesn't matter if non-native ABI libelf exists or not
+# (non-native binary is overwritten, it doesn't matter if libelf was linked to).
+# * elfutils (via libelf) does not build on Windows. gresources are not embedded
+# within ELF binaries on that platform anyway and inspecting ELF binaries from
+# other platforms is not that useful so exclude the dependency in this case.
+# * Technically static-libs is needed on zlib, util-linux and perhaps more, but
+# these are used by GIO, which glib[static-libs] consumers don't really seem
+# to need at all, thus not imposing the deps for now and once some consumers
+# are actually found to static link libgio-2.0.a, we can revisit and either add
+# them or just put the (build) deps in that rare consumer instead of recursive
+# RDEPEND here (due to lack of recursive DEPEND).
