Update README.md - Missing instructions

[ffasilva]

Hi @juanjqo,

I was following the installation instrunctions and noticed a step was missing. I modified the the README.md to add the missing requirement on cpp-interface-coppeliasim installation and fixed the missing dependencies on the example's CMakeLists.txt.

Cheers,
Frederico

Hi @ffasilva,

Thank you for your PR. The instructions I added in the README.md file in the first versions of the cpp-interface-coppeliasim-zmq were meant for developers and not for final users. Therefore, those instructions will be removed from the README.md file in a future version.

Furthermore, the support for MacOS and Windows systems is limited. The official support is for some Ubuntu LTS versions. In such case, the installation instructions are given as follows

sudo add-apt-repository ppa:dqrobotics-dev/development
sudo apt-get update
sudo apt-get install libdqrobotics libdqrobotics-interface-coppeliasim libdqrobotics-interface-coppeliasim-zmq

Kind regards,

Juancho
