Teltonika OpenWRT SDK build error: unknown type name 'RSA'

[conalllaverty]

Hey,
Trying to build the library on the Teltonika SDK (RUT906 version, files here https://wiki.teltonika-networks.com/view/Software_Development_Kit).

Getting the error below for all versions of libwebsockets from 3.1.0 to 4.3.3.

Happening with full and openssl versions, mbedtls version is building.

Tried with openssl 3.0.14 and 3.0.15.

Hm... your Openssl is v3 which is a lot more recent than lws v3, it will not know how to work with it.

Do you need LWS_WITH_GENCRYPTO enabled at cmake? It's not enabled by default on current lws. If not, turn it off.
