qBittorrent & operating system versions

qBittorrent: 4.6.5
Operating system: Debian GNU/Linux 12 (bookworm)
Qt: 6.7.2
libtorrent-rasterbar: github.com/arvidn/libtorrent@8fa55e5a1c

What is the problem?

I'm trying to follow the directions at https://github.com/qbittorrent/qBittorrent/wiki/Compilation-Debian,-Ubuntu,-and-derivatives to compile qBittorrent and the instructions suggest installing Qt from https://www.qt.io/download-qt-installer , which I did, but it's unclear how to install Qt 5 from that. Using the default settings Qt 6.7.2 got installed.

This is an issue because of this step:

cmake -G "Ninja" -B build -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_PREFIX=/usr/local

In particular, that gives this message when it runs:

-- The following features have been disabled:

 * QT6, Build with Qt 6 instead of Qt 5 (default: OFF)

I mean, I'll still need to set the path to Qt (adding Qt5_DIR=~/Qt/6.7.2 to the cmake command would do the trick if I was running Qt5 I guess) but figuring out how to set the path is a bit premature if I can't enable Qt6 builds...

It's -DQT6=ON.

github.com/qbittorrent/qBittorrent@5e81347933/CMakeLists.txt (L25-L31)

With 5.0.0 release Qt6 will became the only option though, so the wiki page need to be rewritten completely.
