Dynamic dependencies are supported by build2 (this is, for example, how we handle auto-generated C/C++ headers) but it's not something that is exposed in ad hoc recipes that are written in Buildscript yet (but is exposed in those written in C++). Our plan is to start with the ability to "ingest" make dependency declarations since quite a few tools are able to produce those. Would something like this cover your use-cases?
