Hi,
Marko tells me he's been having issues with upgrading one of my KF5 ports that
uses the active_variants portgroup to "depend" on variants of one of its
dependencies.
From our exchange:

In short: digikam needs port:opencv with +qt5+contrib. I try to impose that
using
{{{
PortGroup active_variants 1.1
depends_lib-append port:opencv
require_active_variants opencv qt5
require_active_variants opencv contrib
}}}
From what I understand, Marko had opencv+qt5+contrib installed and lost those
variants when port:opencv was upgraded.
I'll leave it to him to post the exact command he used for installing or
upgrading the kf5-digikam port which led to the variant issue, I only have a
part of the trace:

is there something wrong in my way of declaring the variant dependency, or is
this to be expected?
Thanks,
René
