In fact in the thread you give, the developer is saying
that this is a build requirement, not a runtime requirement.
Yes, but a beta tester also says that:
"runtime dependencies: KDE 4 libs (kdelibs5), QCA2 and the openssl
plugin (libqca2?, libqca2-ossl?), libXScrnSaver (libxss?), the Oxygen
Did I get
your correct, that it works, if you install "qca-ossl"?
Yes, just after installing qca-ossl authentication starts to work right.
In fact I would
expect the package called "qca2-ossl", but ...
I agree... strange numbering. Maybe because qca and qca2 are both in use
by different programs while only qca-ossl 2 is in use? It bumped
directly from 0.1 to 2.0 beta...
