In this specific case, the 'static binaries' and 'cross-compilation' aspect aren't relevant, as vanta is a dynamically linked binary with multiple library dependencies; it has to link against libpcap, which also pulls in some infiniband libraries on my system, plus libdbus which pulls in libsystemd, libgcrypt, libgpg-error, libcap, and libs lz4, lzma, and zstd. In fact, the only library that tcpdump links against that vanta doesn't is libcrypto.

Note that none of this has to do with vanta itself; it's solely because it depends on libpcap, and libpcap depends on all of those other libraries. Still, it does mean that cross-compiling isn't notably easier than just building tcpdump itself.
