STEPS TO REPRODUCE 1. Set QCA as a dependency of Kaidan's KDE Craft blueprint 2. Try to build Kaidan for Android by the Binary Factory OBSERVED RESULT An error occurs while trying to build Kaidan for Android by the Binary Factory (https://binary-factory.kde.org/job/Kaidan_Nightly_android-arm64/392/execution/node/18/log/). Kaidan's KDE Craft blueprint (https://invent.kde.org/packaging/craft-blueprints-kde/-/blob/master/kde/unreleased/kaidan/kaidan.py) depends on QXmpp's blueprint (https://invent.kde.org/packaging/craft-blueprints-kde/-/blob/master/qt-libs/qxmpp/qxmpp.py). That depends on QCA's blueprint (https://invent.kde.org/packaging/craft-blueprints-kde/-/blob/master/kdesupport/qca/qca.py) which uses version 2.3.5. It seems that QCA depends on gpg-error leading to the build error. EXPECTED RESULT Kaidan is built for Android by the Binary Factory.
You're trying to build QCA for Android which is not in the supported platforms. So not a bug. If you want to support QCA for Android first step is getting an Android CI.
