# gssapi is just the framework, we really require kerberos v5, so
# look for those headers (the gssapi headers must be there, too)
# The problem with this implementation is that it doesn't allow
# for the specification of gssapi and krb5 headers in different locations,
# which probably ought to be fixed although fixing might raise the issue of
# trying to build with incompatible versions of gssapi and krb5.
