Beat Hangartner 7ec13cbc1a Pin fetched dependencies to commit hashes instead of git tags
CMake fetches pugixml, SingleApplication and the three KDE Frameworks
modules by git tag. A tag is a mutable pointer that its owner can move,
so two builds of the same QElectroTech commit can silently get different
third-party sources, and a compromised upstream account can change what
every builder downloads without anything changing in this repository.
Pinning each dependency to the commit its tag currently points at closes
that, while keeping the tag name in a trailing comment so the intended
version stays readable.

No versions change. Every pinned commit is the one its tag resolves to,
checked with git ls-remote and confirmed by fetching each one and
verifying that git describe reports exactly the tag. The three KDE
modules live in separate repositories and therefore need separate
commits, so the single KF_GIT_TAG variable becomes three per-module
variables; passing -DKF_GIT_TAG=<ref> still selects one ref for all
three, unpinned, exactly as before, and KF_GIT_TAG stays defined so the
build summary in define_definitions.cmake is unaffected.
