Yes, that is correct.

it checks first for libnl-tiny... if you have it installed the
installation script guesses you want to use it. No other reason to
have it around.
See src-plugins/generic/nl80211_listener/CMakeList.txt

checking for libnl-tiny (mostly OpenWRT).

failed.

because of the failed check, see if libnl-genl-3.0-dev is available

Yes it is.

inform the user that libnl3 will be used for nl80211_listener

That looks fine.

The puzzeling question is if nl80211_listener is compiled (so the
nl80211_listener target is available for cmake), why is it not in the
executable.

in src/olsrd2/CMakeList.txt the variable OONF_OPTIONAL_STATIC_PLUGINS
should be set to nl80211_listener when it is not set...

which in turn (in cmake/link_app.cmake, line 41 to 51) should add it
to the "plugin" liust (if it is not already in there).

I have attached a "debug" patch for the build environment... can you
apply it, remove the whole build directory and run "cmake .." on a new
build directory (and post the output here)?
