2023-09-15README.rst: Drop recommendation to install meson using pip3Laurent Pinchart
Usage of pip3 to install meson may result in a different meson version available for the local user and for root. This causes issues when running `meson install` (directly or through `ninja install`): Installing to a system location will request elevated privileges and use the system meson version to install files, which may fail to unpickle data pickled with the meson version for the local user. As all major distributions now provide a recent-enough version of meson, usage of pip3 is not longer needed in most cases, and shouldn't be recommended. Drop it. While at it, update the version of meson listed in the documentation to match the required version.

2022-08-09libcamera: Make IPA module signing recommended instead of mandatoryLaurent Pinchart
Commit b382f67c833d ("libcamera: Make IPA module signing mandatory for the meantime") made openssl and gnutls dependencies mandatory to work around the lack of proper IPA module isolation support, which broke operation without module signatures. This has now been fixed, so IPA module isolation isn't strictly required anymore. There are few use cases for disabling module signing completely, given that the openssl or gnutls dependencies are available on the vast majority of systems and the overheard introduced by isolating all IPA modules when signatures are not available is better avoided. Nonetheless, libcamera should operate properly with forced IPA module isolation, so we can support those use cases. Adopt a middle-ground approach to avoid unintentional isolation by documenting the dependencies as recommended, and warn at meson setup time if they are not found.

Ubuntu 22.04 LTS has been released with meson 0.61.2, and it is easy to install a recent version of meson with python-pip, so let's update the required meson version to get rid of the Android compilation limitation. Additionally, going to meson 0.55 gives the ability to have patch files for git-wraps which is useful for Python bindings. 0.56 brings meson.project_source_root() and meson.project_build_root(), allowing us to get rid of the deprecated meson.source_root() and meson.build_root(). So, let's update the required meson version to 0.56.

2022-01-03meson: reduce required version to 0.53Christian Rauch
Building the libcamera Android layer currently makes use of features from meson 0.55. The core libcamera framework in the default configuration without android enabled uses the 'summary' feature available in 0.53, and is the lowest supportable meson version if the Android HAL is excluded. Ubuntu 20.04 LTS currently provides meson 0.53 and represents an acceptable minimum version to support. Platforms utilising the Android component will have full control over their build environment and can ensure that they provide a more recent version of meson. Reduce the supported meson version for the project to 0.53 to facilitate building on more distributions without having to manually update the meson package. Meson will output a warning that features not available in 0.53 are used if the Android HAL is enabled. This is considered as an acceptable middleground to improve the experience on the latest Ubuntu LTS, until 22.04 LTS is released and provides a newer meson version.

When the libcamera project was started, we had no public git tree hosted on git.libcamera.org. The problem has been addressed a while ago, and the git.linuxtv.org libcamera repository is now a mirror of the main git tree. The mirror is useful to benefit from the linuxtv.org automated compile tests, but it can also confuse users who don't know where the official version is. To try and clarify this, use the git.libcamera.org URL consistently through the project.
