I'm having trouble downloading the slycot library using terminal via pip

So I'm trying to download slycot via pip and I keep getting errors. To be completely honest I'm not totally familiar with terminal prompts and how all that works. Here is what I'm getting when I run, sudo -H pip3 install slycot
Here is what terminal publishes with that command:

The project does not specify a build backend, and pip cannot fall back to setuptools without 'setuptools>=40.8.0' and 'wheel'.

You should consider upgrading via the 'pip install --upgrade pip' command.
I've also tried, pip install cmake and this returns

You are using pip version 19.0.3, however version 20.0.2 is available.

Any help would be appreciated.

You have another error with the installation of slycot, you have a dependency on skbuild.
In order to fix it check this site that gives you the compiled binaries to the skbuild package and try again [and maybe cmake as well]
Try this
pip install scikit-build; pip install cmake
You can read here for more details and ways to make this work.

Can anyone help me?

You should install the Python Image Library(PIL), using the command:
sudo pip install PIL --allow-external PIL --allow-unverified PIL

Check out the virtual environment for python packages. It is really user friendly in pycharm for example and you can test out packages before using up hard drive space.
