Locally on mac I built it. Then I move it somewhere else, now the swiglib is correctly set (before it would still point to the original package dir)

cd conan-center-index/recipes/swig/all

@jmarrec you have to link with dl, as you're clearly using dl functions (https://github.com/conan-io/conan-center-index/pull/8675/files#diff-2faad25d134ffa5e56b13352ef9e70f031c5603072e8b3780b457f196480f03fR14):

@SSE4 You commented pretty much at the same time as I pushed a commit to link to DL. I used the LIBS env variable that is read by swig's configure script, I hope that's ok.
