I know little about gradle and have only just started exploring it, so this is just a question out of curiosity.
It’s supposedly a language agnostic dependency manager and builder, yet it seems to have only found its niche in Java. C/C++ projects could definitely do with dependency resolution…
I worked on a couple commercial C++ applications that used vcpkg. It’s not as convenient as nuget, cargo or npm but it think it is a massive improvement over manually hunting for dependencies.
