# Third-party software

This project is MIT-licensed (see `LICENSE`). `<project>` below is the CMake project name
(`frameassistant`). Builds include or use:

| Component | License | How it is used |
|-----------|---------|----------------|
| [OpenVR SDK](https://github.com/ValveSoftware/openvr) (`libopenvr_api.so`, `openvr.h`) | BSD-3-Clause | Shipped in `lib/`; license in `share/doc/<project>/third-party/openvr.LICENSE` |
| [Eclipse Mosquitto](https://mosquitto.org/) client library (`libmosquitto.so.1`) | EPL-2.0 or EDL-1.0 (BSD-3-Clause) | Linked dynamically. Release packages ship Debian's build unmodified in `lib/`; its copyright file in `share/doc/<project>/third-party/libmosquitto1.copyright` |
| [Qt 6](https://www.qt.io/) (Core, Gui, Qml, Quick, Quick Controls, Wayland/XCB plugins) | LGPL-3.0 (Qt open-source license) | Linked dynamically. Default builds use the system's Qt (not shipped). Bundled builds ship Qt's shared libraries unmodified in `lib/`, `plugins/`, `qml/`: replace them to use another compatible Qt build |

**Bundled builds** (`--bundle-qt`) also ship further shared libraries that Qt depends on,
taken unmodified from Debian. Their copyright and license files are in
`share/doc/<project>/third-party/` (one `<package>.copyright` per Debian package, plus
the license texts they reference). The corresponding sources are available from Debian
(https://sources.debian.org/, package names as in those file names).
