We build libcamera with -Wno-unused-parameter and this doesn't cause
much issue internally. However, it prevents catching unused parameters
in inline functions defined in public headers. This can lead to
compilation warnings for applications compiled without
-Wno-unused-parameter.
To catch those issues, remove -Wno-unused-parameter and fix all the
related warnings with [[maybe_unused]].

The libcamera internal headers are located in src/libcamera/include/.
The directory is added to the compiler headers search path with a meson
include_directories() directive, and internal headers are included with
(e.g. for the internal semaphore.h header)
#include "semaphore.h"
All was well, until libcxx decided to implement the C++20
synchronization library. The __threading_support header gained a
#include <semaphore.h>
to include the pthread's semaphore support. As include_directories()
adds src/libcamera/include/ to the compiler search path with -I, the
internal semaphore.h is included instead of the pthread version.
Needless to say, the compiler isn't happy.
Three options have been considered to fix this issue:
- Use -iquote instead of -I. The -iquote option instructs gcc to only
consider the header search path for headers included with the ""
version. Meson unfortunately doesn't support this option.
- Rename the internal semaphore.h header. This was deemed to be the
beginning of a long whack-a-mole game, where namespace clashes with
system libraries would appear over time (possibly dependent on
particular system configurations) and would need to be constantly
fixed.
- Move the internal headers to another directory to create a unique
namespace through path components. This causes lots of churn in all
the existing source files through the all project.
The first option would be best, but isn't available to us due to missing
support in meson. Even if -iquote support was added, we would need to
fix the problem before a new version of meson containing the required
support would be released.
The third option is thus the only practical solution available. Bite the
bullet, and do it, moving headers to include/libcamera/internal/.

In an attempt to clarify the license terms of all files in the libcamera
project, the build system files deserve particular attention. While they
describe how the binaries are created, they are not themselves
transformed into any part of binary distributions of the software, and
thus don't influence the copyright on the binary packages. They are
however subject to copyright, and thus influence the distribution terms
of the source packages.
Most of the meson.build files would not meet the threshold of
originality criteria required for copyright protection. Some of the more
complex meson.build files may be eligible for copyright protection. To
avoid any ambiguity and uncertainty, state our intent to not assert
copyrights on the build system files by putting them in the public
domain with the CC0-1.0 license.
