If you mean libraries then look up ThirdParty directory in source

[https://github.com/EpicGames/UnrealEngine/tree/dff3c48be101bb9f84633a733ef79c91c38d9542/Engine/Source/ThirdParty](https://github.com/EpicGames/UnrealEngine/tree/dff3c48be101bb9f84633a733ef79c91c38d9542/Engine/Source/ThirdParty)

Each can be used by specific module for example if you wont use WebBrowser widget, CEF is not used
