cppzmq is a header-only library. As such, it is not much useful without zeromq, whose headers it includes. By having zeromq in propagatedBuildInputs, we can simplify dependent expressions. This change is motivated by https://github.com/lopsided98/nix-ros-overlay/issues/255#issuecomment-1487590226. The expressions in nix-ros-overlay are automatically generated and since packages in other distributions where ROS runs need not to explicitly depend on zeromq, the Nix expression should behave the same. This way, nix-ros-overlay will not to have manually patch/overlay the automatically generated expressions. |
