Build bpy

[mrakitin]

A CHX user's requested to build bpy. Here is what we found about this non-standard package:

• requires https://github.com/asottile/future-fstrings to be installed;
• needs cmake to build the package.

I spent some time trying to install cmake in our Debian 7.9 Docker image, but it fails due to the repositories were archived/moved from the standard location. @tacaswell suggested to use deb http://archive.debian.org/debian wheezy main, which worked, but after an attempt to build the package, it turned out the version of cmake was pretty old. Attempted to use conda's version of cmake, which worked better, however the following error was observed:

  -- Found Git: /usr/bin/git (found version "1.7.10.4")
  CMake Error at /conda/envs/bpy/share/cmake-3.14/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

The issue above was resolved by conda install jpeg, however the following error came up:

    -- Found Git: /usr/bin/git (found version "1.7.10.4")
    -- Found JPEG: /conda/envs/bpy/lib/libjpeg.so (found version "90")
    -- Found ZLIB: /usr/lib/x86_64-linux-gnu/libz.so (found version "1.2.7")
    CMake Error at /conda/envs/bpy/share/cmake-3.14/Modules/FindPackageHandleStandardArgs.cmake:137 (message):

That one was resolved by conda install libpng. Next bunch of errors:
