Maybe then the gssapi-dev should also conflict?

In the test if libheimdal exists you first check if --with-heimdal (or
--without) was used and only otherwise do the actual test. [Or you can
test and see if it finds a lib if --with-heimdal was given and file if
not].
That is basically how all the --with/--without constructs wotk that
can also autodetect. There should be plenty of code examples all
around.
