## Overview

meta-qt6 is a Yocto/OpenEmbedded layer that makes Qt 6 and related components available to embedded-image and SDK builds. The principal workflow is a developer configuring a Yocto build to use the layer and select an edition, then using its recipes and package groups to build Qt components. The graph preserves major Qt module families, Python bindings, and SDK support. The README documents layer dependencies and edition controls; source excerpts were not provided, so internal recipe-to-recipe wiring is omitted.

Main entry points: [`conf/layer.conf`](https://github.com/chetan-nmd/meta-qt6/blob/mickledore/conf/layer.conf) (Layer configuration), [`recipes-qt/meta/meta-toolchain-qt6.bb`](https://github.com/chetan-nmd/meta-qt6/blob/mickledore/recipes-qt/meta/meta-toolchain-qt6.bb) (Qt SDK), [`classes/qt6-cmake.bbclass`](https://github.com/chetan-nmd/meta-qt6/blob/mickledore/classes/qt6-cmake.bbclass) (Qt build classes), [`recipes-qt/qt6/qtbase_git.bb`](https://github.com/chetan-nmd/meta-qt6/blob/mickledore/recipes-qt/qt6/qtbase_git.bb) (Qt Base)
