See conda-forge/conda-forge.github.io#1823 for the conda-forge upstream bug.

[traversaro]

I tried a workaround in e8559ce, let's see if it works:
https://github.com/robotology/robotology-superbuild/actions/runs/3098808781

The workaround pins lief to 0.11.5 instead of 0.12.2 (see conda-forge/conda-forge.github.io#1823 (comment)).

[traversaro]

The workaround worked fine, let's suggest it in a PR.

[traversaro]

The workaround works fine for robotology-superbuild, and the actual problem is tracked in conda-forge/conda-forge.github.io#1823 . I think we can close this issue.
