this is because curl 7.64.1 cannot be compiled with latest ldap. this pull request https://github.com/curl/curl/pull/7005 already fixed it. so we can fix it either by update curl, or pin libldap2-dev to old version

It's annoying that the "actual useful" build log wasn't recorded in GitHub Action

after updating curl to 8.13.0 and editing configure.sh to add --with-openssl parameter. now I can run it and now get more error. At least the error is from c2rust-transpile
