Unity builds combine all `.cpp` files into a single one (a single translation unit, TU). This is useful for performance optimization, computer science experiments, or differentiable programming.

Unity builds combine all `.cpp` files into a single one (a single translation unit, TU). This is useful for performance optimization, computer science experiments, or differentiable programming. FYI: A CPU unity build of ImpactX is around 18sec on my laptop (BLAST-ImpactX/impactx#861), for WarpX around 3:30min. In both cases, this refers to the `lib*` of ImpactX/WarpX part. --------- Co-authored-by: Edoardo Zoni <[email protected]>
