Package Requirements Terminal error

> sudo apt-get install cmake gcc "libstdc++6" libx11-xcb-dev libxcb-util-dev libxcb-cursor-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev libfontconfig1-dev libcairo2-dev libgtkmm-3.0-dev libsqlite3-dev libxcb-keysyms1-dev

When trying to run the above commands in the terminal on OSX 10.15.6 i get the following error:
zsh: command not found: apt-get

Any way to make this work ?


I also get an error when trying to build the examples:

Make Error at /Applications/ (message):

  It fails with the following output:
