# apart, and autoconf blamed the next thing it recognised. With the archive
# installed, configure gets far enough to ask for cmocka.

# cmocka is a C unit-test framework, wanted only to build tests that this
# bootstrap does not run -- makepkg is invoked with --nocheck for the whole first
# pass. --disable-unit is tpm2-tss's own switch; the PKGBUILD passes --enable-unit
# in its options array.

# iptables and linux-atm, none of which are here, and libbpf is the dependency
# systemd was already spared for the same reason.
