Please provide the following information

qBittorrent version and Operating System

qbittorrent 4.2.5
Opensuse Tumbleweed

If on linux, libtorrent-rasterbar and Qt version

no Qt
libtorrent-rasterbar is 1.2.9

What is the problem

I had to rebuild my server after a disk failure.
Previously, running same os etc but going through upgrade path, I was able to run up until libsll48 was made the default.
I can't find libssl47 for tumbleweed currently to downgrade.

I now get this error which seems to indicate the symbol doesn't exist in libssl48
/usr/bin/qbittorrent-nox: symbol lookup error: /usr/bin/qbittorrent-nox: undefined symbol: _ZNK10libtorrent5entry4dictB5cxx11Ev

What is the expected behavior

libssl48 would allow for running

Steps to reproduce

install tumbleweed, install qbit from repos

Extra info(if any)

@FranciscoPombal commented on GitHub (Sep 5, 2020):

The problem isn't libssl. It's the way OpenSUSE is packaging libtorrent. The easiest workaround is to build libtorrent yourself in C++14 mode. Duplicate of https://github.com/qbittorrent/qBittorrent/issues/13322, read it for more info.
