# Steam-roll over all executables/libs we have placed in DESTDIR and copy over
# any resolved dependencies from the cross-build (or native MSYS2) environment.
# Then hardlink libraries for sbin... (alternative: all bins in one dir)
# TOTHINK: Are there more dirs to consider? So far we cover bindir, sbindir and
# driverexecdir (e.g. some Linux distros place drivers to /lib/nut while tools
# and daemons are in /usr/bin and /usr/sbin), and cgiexecdir; anything else?..
# Note we hold existance of cgiexecdir as optional, but the name is expected to
# be defined. Other dirs are "just assumed" to exist (that we are not packaging
# some NUT build without drivers/tools/daemons). Subject to change if needed.
# Currently this is handled by a CHECKING... step that should fail if it hits
# anything.
