## Use the following line when 1.10.0 becomes available on Ubuntu. On 4/14/24 it's 1.9.2
#        sudo apt-get install -y doxygen=1.10.0

## xvfb creates a headless X server for us, so we can render snapshot with FLUID

## We need at least Doxygen on macOS. BasicTeX is not enough though.
#        brew install doxygen
#        brew install --cask basictex
#        eval "$(/usr/libexec/path_helper)"
