- 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
Require a ; after RETRANSLATE macros. They are statement-like;
this makes it easier for some of them to be recognized by
clang-format and resolves some existing weird formatting.
- 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.
In spite of there being considerable documentation sometimes in the
config file, we go with CC0 because we don't want the notion of
'derived work' of a config file.
The example `settings.conf` is also CC0. Add some docs to
it while we're at it.
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.
- Let's just have one header definining export- and visibility-
macros for Calamares. They are still selected based on the
export flags (*_PRO), just defined in one header instead of two.
- These methods are used for multi-page view-steps, which are rare.
For all the others, just drop the empty implementation and defer
to the base class.
This is orthogonal to the SKIP_* mechanism already documented
for avoiding modules. If the module is enabled, but its dependencies
are not present, don't bother building the module. This follows
e.g. plasmalnf as an "avoidably heavy dependency".
