Bug#1036522: pytorch-audio: reproducible-builds: build paths trigger differences

[Vagrant Cascadian]

Source: pytorch-audio
Severity: normal
Tags: patch
User: reproducible-builds at lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs at lists.alioth.debian.org

The RPATH contains the build path resulting in different buildid and
various other differences:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/pytorch-audio.html

The attached patch to the upstream tools/setup_helpers/extension.py
fixes this by passing -DCMAKE_BUILD_RPATH_USE_ORIGIN=ON to CMake.

With this patch applied, based on my local tests, pytorch-audio should
build reproducibly on tests.reproducible-builds.org!

Thanks for maintaining pytorch-audio!

live well,
  vagrant
