cdo depends on libQt5 libraries

[Rostislav]

cdo depends on libQt5 libraries while the package does not have any reference.

Way to reproduce:

On a minimalistic Ubuntu (20.04 or 22.04)

    apt update
    DEBIAN_FRONTEND=noninteractive TZ=Etc/UTC apt-get -y install tzdata
    apt install -y cdo

then

$ cdo
/usr/bin/cdo: error while loading shared libraries: libQt5Core.so.5: cannot open shared object file: No such file or directory

In Ideal-world I would like to have a package of CDO suitable for headless application: no X, no QT, no colorful messages etc..

Thank you!
