SSH poll functions not exposed to libssh.so

[Torsten Kuehnel <tdkuehnel@xxxxxxxxxxxxxxxxxxxxx>]

How can i make use of the ssh_poll_* function family ?

[tdkuehnel@ multiboot libncot]$ nm -D /usr/lib64/libssh.so.4.8.4 |grep poll
00000000000226a0 T channel_poll
                 U poll
0000000000017920 T ssh_channel_poll
0000000000017c10 T ssh_channel_poll_timeout
00000000000317b0 T ssh_event_dopoll
0000000000032780 T ssh_get_poll_flags
[tdkuehnel@ multiboot libncot]$ 

For reasons i cannot figure out those functions do not appear in the library. 
In the src/CMakefile.txt poll.c is listed as part of the library sources:

set(libssh_SRCS
  agent.c
  auth.c
  base64.c
  bignum.c
  buffer.c
  callbacks.c
  channels.c
  client.c
  config.c
  connect.c
  connector.c
  curve25519.c
  dh.c
  ecdh.c
  error.c
  getpass.c
  init.c
  kdf.c
  kex.c
  known_hosts.c
  knownhosts.c
  legacy.c
  log.c
  match.c
  messages.c
  misc.c
  options.c
  packet.c
  packet_cb.c
  packet_crypt.c
  pcap.c
  pki.c
  pki_container_openssh.c
  poll.c
  session.c
  scp.c
  socket.c
  string.c
  threads.c
  wrapper.c
  external/bcrypt_pbkdf.c
  external/blowfish.c
  external/chacha.c
  external/poly1305.c
  chachapoly.c
  config_parser.c
  token.c
  pki_ed25519_common.c
)

As cmake is totally new to me, i cannot see any reason for the exclusion 
in either main CMakefile.txt or src/poll.h, src/poll.c files.
