The skip-checking is now in the functions for adding plugins and
subdirectories, so that third-party building should get it
as well, for free. Since AddModuleSubdirectory and AddPlugin
use the newly split-out module, handling SKIP_MODULES and USE_*
consistently across module repositories is now easier.
While here, make accumulating-the-skipped-modules explicit.
- 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.
When CMake runs, configure_file() will clobber the config files in
the build/ directory, which is annoying during testing: you need
to keep making the same edits, or edit the source.
- Introduce new behavior: the config file is **not** overwritten unless
the source file is newer. This means that edits to config files
in the build directory are preserved.
- If INSTALL_CONFIG is **on** then the files are clobbered anyway (the
source is considered new regardless).
- Remove the commented-out cruft and the whinging
- Fix use of COMPILE_DEFINITIONS with a list passed in
- Remove unused arguments (TYPE, TARGET)
- Document calamares_add_library
- Document how to use COMPILE_DEFINITIONS (in calamares_add_plugin)
Switching to INSTALL_CONFIG=OFF breaks tests by not having them
in the build directory. Some logic was coupling not-installing
to not-using-in-build-dir too closely.
Although the NO_INSTALL keyword could be specified for
Calamares plugins, it didn't actually do anything. Now
it does. A NO_INSTALL module does not install configs
or libraries.
Since we install the CMake files now, also put license headers in them.
These files are intended to help plugin and branding component authors
write them in a simple Calamares-idiomatic way.
