Shall we go for an approach like Debian's update-alternatives?\r\n\r\nHere's my proposal.\r\n\r\nWe have `libblas=3.8.0=netlib` with `libblas.so.3` and downstream packages compile and link against this library. openblas and mkl also provides `libblas=3.8.0=openblas`, `libblas=3.8.0=mkl` conda packages with build string openblas and mkl and in those packages, they symlink/hardlink `libblas.so.3` to `libopenblas.so` or `libmkl_rt.so`\r\n\r\nIn this way, there needs to be one variant of the downstream package and the user can pick whatever blas implementation they need.\r\n\r\ncc @conda-forge/core, @mingwandroid "},"comment":{"url":"https://api.github.com/repos/conda-forge/blas-feedstock/issues/comments/444380309","html_url":"https://github.com/conda-forge/blas-feedstock/issues/15#issuecomment-444380309","issue_url":"https://api.github.com/repos/conda-forge/blas-feedstock/issues/15","id":444380309,"node_id":"MDEyOklzc3VlQ29tbWVudDQ0NDM4MDMwOQ==","user":{"login":"mingwandroid","id":1042804,"node_id":"MDQ6VXNlcjEwNDI4MDQ=","avatar_url":"https://avatars1.githubusercontent.com/u/1042804?v=4","gravatar_id":"","url":"https://api.github.com/users/mingwandroid","html_url":"https://github.com/mingwandroid","followers_url":"https://api.github.com/users/mingwandroid/followers","following_url":"https://api.github.com/users/mingwandroid/following{/other_user}","gists_url":"https://api.github.com/users/mingwandroid/gists{/gist_id}","starred_url":"https://api.github.com/users/mingwandroid/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mingwandroid/subscriptions","organizations_url":"https://api.github.com/users/mingwandroid/orgs","repos_url":"https://api.github.com/users/mingwandroid/repos","events_url":"https://api.github.com/users/mingwandroid/events{/privacy}","received_events_url":"https://api.github.com/users/mingwandroid/received_events","type":"User","site_admin":false},"created_at":"2018-12-05T07:00:14Z","updated_at":"2018-12-05T07:00:14Z","author_association":"NONE","body":"Thanks @isuruf, some of the AD team are out of action at present but rest assured this important work will not be forgotten about!"}}
