antimony doesn't build with cmake 3.11

[rnhmjoj]

Antimony stopped building when cmake was updated from 3.10.2 to 3.11.2. This is the log:

builder for '/nix/store/w5rsz9wdinw8i8fphy8v6fcyx2464iih-antimony-2018-07-10.drv' failed with exit code 1; last 10 log lines:

Taken by itself, that doesn't look like a CMake issue – it looks like a problem finding libraries.

Can you look in your system to see what boost::python3 is named, and open a PR that adds it to this list (if that fixes the problem)? I'm not sure why a CMake update would break things, but perhaps something else got updated or renamed at the same time.

I don't know what boost::python3 is supposed to be but the nix package builds antimony with python3 and boost.override { python = python3; }. Since the package used to work not too long ago I did a git bisect in the nixpkgs repo and the first bad come up as https://github.com/NixOS/nixpkgs/commit/75e78eda1fd85ac7306acfe597eb5f55b7f60a55, so I thought cmake was the issue.

I won't be able to get into the weeds of debugging nix packages, perhaps you can ping the original packager?

My specific suggestion is to set up an environment with all of the dependencies installed, check in /usr/local/lib (or wherever NixOS puts libraries) for something like libboost-python???, then add that specific naming convention to the list of searched names.

I realized python support has been disabled by default in the boost package since libbost_python3.so was missing. Something else must have inferfered when bisecting. Thank you and sorry for the trouble.
