qBittorrent uses the Qt framework as the basis for its GUI.

- qBittorrent 4.4.x requires at least Qt 5.15.2.
- At the time of writing, the current `master` branch requires at least Qt 5.15.2.
- qBittorrent 5.1.x requires at least Qt 6.5.0.
- At the time of writing, the current `master` branch requires at least Qt 6.6.0.

Many distributions, in particular Debian, Ubuntu (especially LTS releases), and their derivatives don't provide up-to-date Qt packages in their repositories or are very slow in updating them.
In such cases, you must get them from somewhere else, such as the official installer from the [Qt website](https://www.qt.io/download-qt-installer) (unfortunately, this method requires the creation of an account, but you can just use a throwaway email), or a PPA you trust in the case of Ubuntu and other distributions that support that installation method.

For Debian and Ubuntu versions that include sufficiently up-to-date Qt packages, you can just install the following packages from the official repositories:

```bash
sudo apt install --no-install-recommends qtbase5-dev qttools5-dev libqt5svg5-dev
sudo apt install --no-install-recommends qt6-base-dev qt6-base-private-dev qt6-tools-dev qt6-svg-dev
```

cd libtorrent

cmake -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr/local
cmake --build build
sudo cmake --install build
cd build
ninja
sudo ninja install
```

The install step will install libtorrent to the chosen prefix (`/usr/local`, in this case), and generate an `install_manifest.txt` file in the build folder that can later be used to uninstall all installed files with `sudo xargs rm < install_manifest.txt`.
