There is a script inside libcamera that checks whether the sources are in a git tree. If yes, the version obtained by git describe is used. As a fallback, the meson project version is used. As a consequence, the version of our BSP is leaked into libcamera. I haven't tested this GIT_CEILING_DIRECTORIES approach but it seems to me that it would do the trick. > Given this is a global change, does anyone see a potential problem? Can't be the judge of that, though. Best regards, Michael
