First quit LibreOffice Writer if you have it running. Next, perform the following commands.
sudo dnf install texlive-cm-unicode
mkdir -p ~/.fonts/
dnf repoquery -l texlive-cm-unicode | egrep '\.otf$' \
| xargs -I{} ln -s {} ~/.fonts/
fc-cache -f ~/.fonts/Now start LibreOffice Writer and you'll find the Computer Modern Unicode LaTeX fonts in the font list of LibreOffice Writer. Note that they will be named like "CMU", not "Computer Modern" or anything like that.
