    ARROW-8602: [C++][CMake] Fix ws2_32 link issue when cross-compiling on Linux
    
    With this patch I can cross-compile arrow from a Linux system, in 
particular I can compile Windows binaries on a Linux system (using 
https://binarybuilder.org/). I hope to eventually be able to use things from 
Julia with this.
    
    My best guess is that the inconsistent casing of `ws2_32` in the various 
build files/systems is no problem when compiling things on Windows because file 
systems there tend to be case insensitive.
    
    Closes #7001 from davidanthoff/fix-crosscompile
