 This repository, although called `toxcore`, in fact contains several libraries besides `toxcore` which complement it, as well as several executables.

Here is the full list of the main components that can be built using the CMake, their dependencies and descriptions.

 Library dependencies are listed in the [components](#components) table. The dependencies need to be satisfied for the components to be built. Note that if you don't have a dependency for some component, e.g. you don't have `libopus` installed required for building `toxav` component, building of that component is silently disabled.
 
 
-Be advised that due to the addition of `cmp` as a submodule, you now also need to initialize the git submodules required by toxcore. This can be done by cloning the repo with the addition of `--recurse-submodules` or by running `git submodule update --init` in the root directory of the repo.
