Does it link on ESP32

I am getting linker errors.

https://github.com/warmcat/lws-esp32-factory/tree/master/components/zlib/contrib/minizip

is not building for esp32.

I have no idea what you're trying to do, but the zlib component builds fine if you build it as part of, eg, the factory sample. You seem to be building something in esp-idf... either way it's not my problem.
