Currently tools.deps does not support jars that package their own native libraries.  

chrisn@chrisn-dt:~/dev/tvm-clj/tvm/build$ clojure -Sdeps '{:deps {techascent/tech.opencv {:mvn/version "1.2"}}}'
Clojure 1.9.0
user=> (require '[tech.opencv :as opencv])

A form of this works from leiningen and java.

Here is a good chunk of the leiningen code to do this:


A lot of java software does this:

1.  They try to load the library from the system if possible.
2.  Failing that, they extract the library included in the jar to a temporary location and try to load this.

This, I believe, is the best pathway although it is somewhat outside the purview of tools.deps; perhaps there could be a companion library?
