Running CMake on it caused the following error:
error: Target "publisher" links to target "Qt5::DBus" but the target
was not found. Perhaps a find_package() call is missing for an
IMPORTED target, or an ALIAS target is missing?
Add the missing DBus component.
This is the convention suggested in the Sphinx documentation and is
already used in several other places in the CMake documentation.
Update a few places where we were using other characters.
Add an introduction about the use of different package types, and the
ability to use Qt 4 and 5 versions together in a single buildsystem.
Add a section about automatic linking of the qtmain.lib library and
how to disable it.
