This guide will cover building and deploying the native plugin com.unity.webrtc depends on.
Install dependencies to make development environment.
On windows, chocolatey is used to install.

cd cmake-3.18.0
./bootstrap && make && sudo make install
# Install pkg-config, zip
sudo apt install -y pkg-config zipTo build plugin, you need to execute command in the BuildScripts~ folder.
- BuildScripts~/build_plugin_android.sh
- BuildScripts~/build_plugin_mac.sh
- BuildScripts~/build_plugin_ios.sh
- BuildScripts~/build_plugin_linux.sh
- BuildScripts~/build_plugin_win.cmd
The WebRTC project properties must be adjusted to match your environment in order to build the plugin.
Set the Unity.exe path under Command and the project path under Command Arguments. Once set, during debugging the Unity Editor will run and breakpoints will be enabled.
When you run the build, webrtc.dll will be placed in Packages\com.unity.webrtc\Runtime\Plugins\x86_64. You should then be able to verify the following settings in the Unity Inspector window.
