For completeness:

For "ld" on macOS the order does not matter. For "ld" on Linux the order 
does matter, but, if necessary, the following flags can be used to link 
libraries in any order: "--start-group" and "--end-group". Those flag 
will cause the linker to search the libraries repeatedly to resolve 
undefined symbols.
