OpenSSL 3.5 (first shipped in wrynose) made HMAC_CTX a fully opaque type by removing its struct definition from the public headers. It was deprecated since OpenSSL 3.0 but the struct remained visible until 3.5.
libwebsockets uses HMAC_CTX_new() to detect which form to use in its lws-genhash.h public header: if found it uses HMAC_CTX *ctx (pointer), otherwise it falls back to HMAC_CTX ctx (embedded struct). In cross-compilation the CMake CHECK_FUNCTION_EXISTS probe for HMAC_CTX_new can fail due to native libraries being incorrectly pulled into the aarch64 link test, causing the function to be reported as not found. Before OpenSSL 3.5 this was a silent failure: the fallback embedded struct still compiled fine. With OpenSSL 3.5 the fallback now fails with "field has incomplete type". Force LWS_HAVE_HMAC_CTX_new=ON so the pointer form is always used.
