OK. Let's stick with a "depends on" for now then. I'm not sure the
switch to a virtual package will require a "depends on". Normally you
can indeed only "depends on" a virtual package. But for this specific
case, we can have a virtual package that automatically selects the
right implementation depending on the selected platform, so this
virtual-package could be selected (like we can select jpeg or zlib or
openssl).

Best regards,
