When I query the list of RADIUS fields from tshark, I see a different

Why is the environment variable WIRESHARK_RUN_FROM_BUILD_DIRECTORY
necessary for the in-source CMake build but not in any other case?
There's code in epan/filesystem.c that is able to detect (based on the
presence of the .libs directory) that we're being run from an
autotools-based build directory (thus making the environment variable
not necessary). No such code (yet) exists for cmake. Or Windows, for
that matter...
