It uses a non-standard build tool (UBT).Unreal Engine comes into play because it is a C++ cross-platform framework that adds some additional layers of complexity: There will be a second article that we’ll focus on the source code available scenario. The focus of this article will be - in fact - on the packaging problems that are very likely to occur when integrating a third-party library into a C++ project and how - when possible! - to solve them. There’s also a third scenario, that’s when the library is header-only, but the integration is very easy and there are no packaging problems (more or less…). The third-party library source code is available and we have to compile it.The third-party library comes as a pre-built binary.Every Operating System (OS) has its own peculiarities when it comes to integrating third-party software, but apart from the OS, there are only 2 possible scenarios when it comes to the integration of a third-party library in a C++ software: The Unreal Build Tool (UBT) official documentation explains how to integrate a third-party library into Unreal Engine projects in a very broad way without focusing on the real problems that are (very) likely to occur while integrating the library.
