cqrlog needs gtk2 but newer distributions only have gtk3

[dl7oap]

a problem when installing cqrlog on Ubuntu 19.04 or Ubuntu 19.10 is the libgtk. there is following error message: cqrlog: error while loading shared libraries: libgdk-x11-2.0.so.0: cannot open shared object file: No such file or directory cqrlog needs libgtk2.0-0 but the newer Ubuntu distributions only have gtk3 libgtk3.0.

this can be solved by installing libgtk2 manually before starting cqrlog

sudo apt install libgtk2.0-0
sudo apt install libcanberra-gtk-module

it should be discussed or searched for a possibility, so cqrlog get installed out-of-the-box. maybe cqrlog can switch to gtk3. but then users with older distributions will have trouble and have to install gtk3 manually.

maybe there is a way cqrlog installation can take care, so that the right gtk library get installed automaticly. or there should be a official installation script, which takes care for these topic.
