# - Try to find LibNETCONF2
# Once done this will define
#
# LIBNETCONF2_FOUND - system has LibNETCONF2
# LIBNETCONF2_INCLUDE_DIRS - the LibNETCONF2 include directory
# LIBNETCONF2_LIBRARIES - Link these to use LibNETCONF2
# LIBNETCONF2_VERSION - SO version of the found libNETCONF2 library
# LIBNETCONF2_ENABLED_SSH - LibNETCONF2 was compiled with SSH support
# LIBNETCONF2_ENABLED_TLS - LibNETCONF2 was compiled with TLS support
