 This is not the default as there is no general way to know its value and depends on distribution (`/usr/lib`, `/usr/libexec`, or NixOS which isn't FHS compliant at all). System programs usually have a hard-coded path looking for `lib`. If you are a package maintainer for a distribution, setting this value when compiling, so it fits into your distribution standard.
 
 If you installed the module with `cargo install`, the binary will be placed in `bin` subdirectory under Cargo's home which should be in the `PATH` anyway. Cargo has no option to place in subdirectories with other names.
