   1 # - Try to find GSSAPI
   2 # Once done this will define
   3 #
   4 #  KRB5_CONFIG - Path to krb5-config
   5 #  GSSAPI_ROOT_DIR - Set this variable to the root installation of GSSAPI
   6 #
   7 # Read-Only variables:
   8 #  GSSAPI_FLAVOR_MIT - set to TURE if MIT Kerberos has been found
   9 #  GSSAPI_FLAVOR_HEIMDAL - set to TRUE if Heimdal Kerberos has been found
  10 #  GSSAPI_FOUND - system has GSSAPI
  11 #  GSSAPI_INCLUDE_DIR - the GSSAPI include directory
  12 #  GSSAPI_LIBRARIES - Link these to use GSSAPI
  13 #  GSSAPI_DEFINITIONS - Compiler switches required for using GSSAPI
