It would also be preferred to use `RPATH` instead of `RUNPATH`, as the prior has precedence over `LD_LIBRARY_PATH`, which users might have set.\n\n### Has this already been discussed elsewhere?\n\nNo response given\n\n### Links to previous discussion of this feature:\n\n_No response_\n\n\u003c!-- gh-linked-prs --\u003e\n### Linked PRs\n* gh-128470\n* gh-128645\n* gh-129506\n\u003c!-- /gh-linked-prs --\u003e\n","author":{"url":"https://github.com/FFY00","@type":"Person","name":"FFY00"},"datePublished":"2025-01-04T04:37:47.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/128469/cpython/issues/128469"}
