I think you can drop debian-cross@l.d.o again. There are two major ways of bootstrapping. It's the cross bootstrap (which is what I work on) and the native bootstrap (mostly Daniel Schepler). On debian-cross we mostly care about cross bootstrap (surprise!). Since cmake is marked Multi-Arch: foreign, we can (almost) always B-D on it without negatively impacting cross builds. What probably is impacted by this dependency is native bootstrap. My understanding of native bootstrap is too limited to explain how (severe) it is impacted. Since apt Build-Depends: cmake, it already is entangled in some way. I'd hope that adding another cmake dependency is not ending the world. If you want to add a build profile, do not use stage1. This profile has become meaningless and is thus deprecated. We are moving to functional build profiles. Use pkg.libzstd.nocmake or something even more descriptive. Last but not least, I second the idea of improving cmake such that it can deal with pkg-config files. Helmut
