# - Try to find GSSAPI
# Once done this will define
#
# KRB5_CONFIG - Path to krb5-config
# GSSAPI_ROOT_DIR - Set this variable to the root installation of GSSAPI
#
# Read-Only variables:
# GSSAPI_FLAVOR_MIT - set to TRUE if MIT Kerberos has been found
# GSSAPI_FLAVOR_HEIMDAL - set to TRUE if Heimdal Kerberos has been found
# GSSAPI_FOUND - system has GSSAPI
# GSSAPI_INCLUDE_DIR - the GSSAPI include directory
# GSSAPI_LIBRARIES - Link these to use GSSAPI
# GSSAPI_DEFINITIONS - Compiler switches required for using GSSAPI
