I tried to build it using your commands, but I'm getting a CMake error. I'm attaching the terminal output and the `configure.log` file.

Anyway, don't waste your time trying to help me—I don't know anything about compiling, and I was only able to compile the classic CinGG because I copied and pasted the commands. It's up to you whether it's worth trying to figure out my problem or just letting it go.

Regarding the tests:

Overlay plugin: Sorry, it's my fault. I had forgotten that the “overlay plugin” is a shared effect, and I had placed it only on the top track.

Videoscopes: It's amazing! I don't know how to thank you.

Drop-down list: All OK, thanks.

PS: I tried launching CinGG-QT6 with `QT_QPA_PLATFORM=wayland`, and it seems to be working. But I'm not sure if I'm running on Wayland or XWayland.
