Thei package build qt-openzwave from the head of the default upstream
github branch.

It depends on two other packages in the AUR

- *openzwave-git* because the stable-release *openzwave* package lacks
  features needed for the active development of *qt-openzwave*.
- *google-breakpad-git* for breakpad debugging support, though this
  could be patched out of the build.

There are some inconsistencies and bugs in the upstream qt-openzwave
build scripts which the developers [seem to be aware of](https://github.com/OpenZWave/qt-openzwave/issues/9).

Notably, some dependencies (breakpad) are strictly searched relative to
the qt-openzwave source directory instead of through pkg-config or
tunable comand line options to qmake. This is fixed in the interim by a
patch.

Also, the `ozwdaemon` install prefix is hard-coded. It is not possible
under qmake to override this prefix to meet Arch's guidelines without a
patch.
