The preferred way to check for - and handle - GSSAPI/krb5 is with
pkg-config. So, for instance, on my system:

rharwood(at)thriss:~$ pkg-config --exists krb5-gssapi
rharwood(at)thriss:~$ echo $?
0
rharwood(at)thriss:~$ pkg-config --libs krb5-gssapi
-L/usr/lib/x86_64-linux-gnu/mit-krb5 -lgssapi_krb5
rharwood(at)thriss:~$ pkg-config --cflags krb5-gssapi
-isystem /usr/include/mit-krb5 -isystem /usr/include/mit-krb5

In the past, this was done using krb5-config, but this has become
increasingly difficult to continue to make work (and krb5-config is not
nice code to work with).
