Cl-update and emerged packages

I emerged the following packages with a script on the latest calculate linux cinnamon:
emerge -av media-sound/audacious
media-plugins/audacious-plugins
app-editors/vim
app-editors/nano
dev-vcs/git
net-im/telegram-desktop
media-fonts/inconsolata
media-fonts/hack
media-fonts/fira-code
media-libs/x264
media-libs/x265
sys-block/gparted
sys-apps/gnome-disk-utility
media-video/vlc
media-video/libva-utils
app-office/lyx
app-text/texlive
net-firewall/firewalld

Whenever I do cl-update, it asks me if I wish to “unmerge” this installed packages.

What do I have to do to have my installed packages not be subjected to an un-emerge.
Thanks in advance for help.

You need to add packages to the world file:

emerge --noreplace <atom>

Thank you!
I wish all those who celebrate the Nativity a peaceful and joy-filled celebration!
