ninja: build stopped: subcommand failed.

to prevent the linking error from happening I had to statically disable calls to dl::tool::cache::autoload_func: https://github.com/espressif/esp-dl/compare/master...zRedShift:esp-dl:master

Also some fixes for printf warnings/errors

@zRedShift I guess you are not using correct version of idf. Try by using idf Version 4.4

[zRedShift]

@alibukharai You're right, I was using v5.1 (esp-idf master), any plans to move this library to support esp-idf v5.0 now that it's been released?

[alibukharai]

@zRedShift Yes, In future v5 will be avaiable for esp-dl. :)

please check branch: idfv5.0
