- Modules and plugins don't need to mention libcalamares themselves
for linking -- we can do that automatically. Use the IMPORTED names
so that it works in Calamares main repo and external repositories.
- Complain about unknown module types.
Some tests -- notably the keyboard module -- need to have the
QRC for the module loaded as well (e.g. because of data in the
QRC). Add a RESOURCES parameter to calamares_add_test()
like calamares_add_plugin() already has, to build the
resources into the test.
Keyboard test now passes, since it was missing the data for
lookups before.
- 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 intended license for the CMake modules is BSD-2-Clause;
there's no desire to restrict what can be done with these,
and CMake modules are generally 2-clause licensed.
