This is because with the split packages of the Meson build, we simply have no idea what directory the binaries will be installed in when we build the library. In the process of doing so, consolidate and make more sophisticated the logic to cope with a few corner cases (e.g. `NIX_BIN_DIR` exists, but no binaries are inside it).
