I faced the exact issue. I commented out the following lines from curl\lib\vtls\openssl.c

if(data->set.ssl_enable_npn)
  SSL_CTX_set_next_proto_select_cb(connssl->ctx, select_next_proto_cb, conn);

and then build was successful. Not sure if it's a bug but somehow I managed to get a temporary fix.

The reason I feel it's a bug is because: SSL_CTX_set_next_proto_select_cb() is declared in openssl\include\Ssl.h but I cannot find its definition anywhere.
