unbound 1.6.1: Linking against libevent2

Hi,

this was triggered by unbound-users@unbound.net - it seems that the
'configure'-option '--with-libevent-support' is not enough:

***SNIP***
...
When building unbound with --with-libevent support, the make
install phase should also call make unbound-event-install or else
unbound-event.h does not get installed and the header file for
using the unbound event functionality is not available.
...
This install is triggered by the option --enable-event-api. Just
enabling --with-libevent does not trigger the install by itself.

Best regards,
Wouter
...
***SNAP***

I built 'unbound' this way - its running without any problems so far.

Best,
Matthias
