Hi, FWIW, graphviz can also be moved to Build-Depends-Indep now, it's only used as a build dependency for generating the call graph images in the C++ docs, see: https://github.com/libvips/libvips/blob/v8.15.2/cplusplus/Doxyfile.in#L21
Also, looking at the dependency list, I think libice-dev can be removed. AFAIK, libvips does not depend on that (perhaps it's a remnant of nip2?). Cheers, Kleis
