Build without requiring BlossomV?

[Robbybp]

I would like to use this package's implementation of the Hungarian algorithm, but cannot build it as I cannot build the BlossomV dependency. This appears to be because the link to the BlossomV code that BlossomV.jl uses has been taken down (see mlewe/BlossomV.jl#23). Is there a way to make BlossomV an "optional dependency"?

[Robbybp]

Based on some cursory reading, it seems "optimal dependencies" aren't really a thing in Julia. However, am I correct to assume, based on the BlossomV.jl issue, that this package won't build for anybody who doesn't already have the BlossomV library?

I was having some related issues. Currently there is a bounty worked on for (1) having a simple julia implementation of blossom that can be used here so we do not need to worry about BlossomV issues and (2) moving blossomv to an optional dependency (a "weakdep" as a "pkgext" in julia) so that one still has access to faster algorithms if they can install the non-opensource blossomv

Yes a weakdep would be a very good idea.
