Qt version

[k-morozov]

I am trying to build qBitTorrent for Linux/Ubuntu.
https://github.com/qbittorrent/qBittorrent/wiki/Compilation:-Debian,-Ubuntu,-and-derivatives

At the time of writing, the current master branch requires at least Qt 5.15.2.
It says here that 5.15.2 is the minimum version.

But when I build it, I see the next:

CMake Error at src/CMakeLists.txt:56 (find_package): Could not find a configuration file for package "Qt5" that is compatible with requested version "5.15.2". The following configuration files were considered but not accepted: /usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.12.8 /lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.12.8

The following configuration files were considered but not accepted:

/usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.12.8
/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.12.8`

I assume that there is a mistake in the documentation or in cmake. Tell me, am I right?
If this is a mistake, maybe I should add conan? I can do that.
