No sys dependencies needed when running the CLI

[da-kami]

When building the project on the raspberry I noticed that we currently have two dependencies, openssl and protobuf, which might also have to be available at runtime.

I temporarily solved this by installing the necessary libraries on the raspberry:

# install openssp dependencies
sudo apt install -y libssl-dev
# install protobuf dependency
sudo apt install -y protobuf-compiler

In order to allow easy use of the CLI we have to ensure that there are no external dependencies.

Theses dependencies are only needed to build the project. This is why they are postfixed with -dev and -compiler.
Did you try to uninstall them and run the binary?

Are you certain about this? -dev just means that we are installing the headers in addition to the shared library. Usually that is necessary because some project wants to link against this shared library which implies that the library still needs to be present at runtime.

#218 takes care of the openssl dependency.

I couldn't find any mention of the protobuf compiler within the dependency tree. Are you sure that this one is required?
