# * 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).
