The LibreOffice build system provides integration with a set of IDEs including Kdevelop, Eclipse, Vim/YouCompleteMe, QtCreator and Visual Studio. This allows developers on all platforms to use their preferred environment and still IDE features like code-completion on many of them without the need to manually maintain all of those. Gbuild, the LibreOffice build system, exports most relevant data about this to JSON files, which then can be used to create project solutions on multiple IDEs. This talk describes how we got there, past and future challenges and opportunities. It might also be of interest for other projects interested in providing something similar.
