Something we can't do (imagine what would happen if kcoreaddons was
building - everything else would sit waiting for it to finish and so
on down the line).

The Jenkins mechanism for this is known as Upstream/Downstream jobs -
and I believe if the information is made available then Jenkins will
wait for upstream builds to finish and trigger downstream builds (a
main reason why we don't have this setup - a kcoreaddons build would
trigger a full CI rebuild effectively, something which takes many
hours).

You can already see that mechanism at work for part of Frameworks, and
the cascade that creates.

Do note that PIM has required Sysadmin intervention to fix it's CI on
enough occasions that i've lost count, due to CMake library version
bumps, unnecessary so-version bumps, binary incompatibility (requring
intermediary libraries to be rebuilt) and sudden Qt version dependency
bumps without outside consultation. It's not only CI that has issues
with PIM buildability as well - other KDE developers have issues with
it as well often being the sole source of failures in their
kdesrc-build runs.

In regards to Plasma - i've already discussed that with them, their
breakages are due to dependence on Qt 5.6 which the stable-kf5-qt5
branch group doesn't have available as it runs 5.5. The change in
stable-kf5-qt5 branch groups was normal - they're preparing for a
release I believe. This is something which will be fixed.

Probably needs a rebuild of Akonadi - newer Qt won't like the plugin
being built against an older Qt even when it's within the same patch
version family.
Qt is known to be binary incompatible like this across even patch
releases (i've no idea why they enforce this silly restriction)

The installation of given dependencies is guaranteed to be consistent
by the method the CI system uses to build, install and distribute
projects - so this isn't within the installation of Qt.
Between projects though is another story - the Akonadi SQLite plugin
likely being the cause here.
