JuanJakobo/Pocketbook-ZIM-Reader — reverse-engineered prompt

Build me a simple PocketBook app that can read offline ZIM files on the device. I want to copy the app into the PocketBook applications folder, launch it once so it creates its own ZIM Reader folder, then drop ZIM files in there and search across them.

The main thing is a straightforward search screen that looks and feels usable on an e reader. It should find results from multiple ZIM files and let me open a selected result in the ebook reader app, with KOReader as the recommended option. Keep it focused and practical, not fancy.

Use C++ and the existing PocketBook style build setup, and rely on the openZIM libzim library for working with ZIM files. Please make the project buildable with CMake and include whatever small scripts or setup are needed to package the final ZIM Reader app for a PocketBook. Look up current PocketBook and libzim docs online if you need to.
