[RdKafka] OpenSSL not available at build time #954
Description
The Kafka SASL_SSL authentication method is not available or working, even though the openssl extension is enabled: Unsupported value \"SASL_SSL\" for configuration property \"security.protocol\": OpenSSL not available at build time.
When running the command: php -r "echo (new RdKafka\Conf())->dump()['builtin.features'];" it's possible to see that the ssl option is not available.
I tried to force openssl through the --with-libs option, but it still didn't work, for example: bin/spc build --build-cli "openssl,rdkafka,zlib" --with-libs="openssl,librdkafka"
