When using Transgui and your are receiving the following OpenSSL library error:

It can easily be fixed by installing libssl-dev.
apt install libssl-dev
Worked for me on the following setup:
- Linux Mint 20.1
- transgui 5.18.0
- transmission-daemon 2.94 (installed with the swizzin script on debian buster)
