Hi, The object file is supposed to be automatically linked into your application when you link to the static library target. That's handled by the qt6_add_resources call that qt6_add_shaders call, and it assumes you use target names for linking, and not file paths. If it doesn't, i suspect you're doing something special in your project. Are you perhaps adding the shadert to a static library in one project, and then trying to reuse the static library in a different project?
