Generate a version string, and provide a global string object which allows applications to interrogate the current libcamera version information. The version header is automatically updated by meson on each build. The string roughly follows the semver [0] conventions of major.minor.patch-label as a value. [0] https://semver.org/ A script (utils/gen-version.sh) is provided which is modelled upon the processing from autoconf's git-version-gen. The gen-version.sh script will look for tags in the form vX.Y as starting points for the version string. While the repository does not have any matching tags, v0.0 will be assumed, resulting in versions with both major and minor being set to '0', and the patch count resulting from the number of patches in the history to that point. Finally, a uniquely identifying shortened hash is provided from git: v0.0.509+0ec0edf7 Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Kieran Bingham <kieran.bingham@ideasonboard.com>
