 Current state, we need:
 
- - `cmake` as the build system.
- - `qt6` with `qt6-multimedia` since we use it for playback.
- - `taglib` to get the audio file properties.
- - `kissfft` for FFT support (will be downloaded at configure-time by `cmake`).

+  - It's suggested to use the same FFmpeg version that Qt Multimedia uses, so we can reuse the FFmpeg library binaries that Qt uses.
+    - You can know the version by checking [Qt documentation's FFmpeg attribution page](https://doc.qt.io/qt-6.9/qtmultimedia-attribution-ffmpeg.html)
 
 Then we can build it with any proper c++ compiler like g++ or msvc.
