When using
basix
as a third-party library within aC++23
compliant project the include ofmdspan
will trigger a default use of the bracket operator[]
, howeverbasix
currently relies on parentheses based element access and thus compilation is not possible (especially due to presence ofmdspan
based computations in thebasix
headers).This (re-)adds the public config for the
mdspan
headers. Previously removed after a comment at #844 (comment).Since
basix
does not install any headers during the python build, we do not need to (re-)add this in the Python config.
