- do not link (explicitly) to Calamares libraries, the CMake
functions do that automatically.
- while here, tidy and remove commented-out-bits
- while here, remove unneeded includes
- point to main Calamares site in the 'part of' headers instead
of to github (this is the "this file is part of Calamares"
opening line for most files).
- remove boilerplate from all source files, CMake modules and completions,
this is the 3-paragraph summary of the GPL-3.0-or-later, which has
a meaning entirely covered by the SPDX tag.
The build instructions are not that interesting, it's a toss-up
between CC0 and BSD-2, but because other CMake bits are BSD-2-Clause,
apply that to more CMakeLists. The copyright date isn't all that
accurate, but these are just inconsequential files.
While here, tidy up and get rid of some useless intermediates.
This makes it possible to remove QML from Calamares, possibly yielding
a smaller, lighter installer; it takes with it the nice slideshow,
modern configurable navigation and the QML UIs built for various modules.
By default, WITH_QML is on and the "normal" feature set is retained.
- look for Qml modules only when WITH_QML is on (the default)
- look for Network, since that's pulled in only implicitly
- disable the QML Calamares models (modules/*q) if no QML is
enabled; longer-term plan is to merge the **pages** back to
the "upstream" modules, and have things be run-time switchable,
but that's not here yet. Also disable the notesqml module when
QML is off.
