How to add apt dependencies to setup.py

Question

I have a module called ModernGL

I want to add the following modules as dependencies for my module when installing on Ubuntu. I have some installing notes already:

apt-get install python3-dev libgl1-mesa-dev libx11-dev
python3 setup.py install

• How can I detect if python3-dev, libgl1-mesa-dev and libx11-dev is not installed?

• Can I add these packages as a dependency in the setup.py?

• How can I print a message from setup.py properly to let the user know what to install?

Some files that are relevant:

• The setup.py
• The README with ubuntu install notes

Answer 1

A while ago I added these lines to a shell script:

INSTALL=
for P in gnome-common yelp-tools yelp-xsl; do
    if ! dpkg -l $P >/dev/null 2>&1; then
        INSTALL="$INSTALL $P"
    fi
done
if [ -n "$INSTALL" ]; then
    echo "To use this script, please install required packages by running this command:"
    echo "\nsudo apt install$INSTALL\n"
    exit 1
fi

The same approach can be applied with Python code, I suppose.
