# From gcc's documentation:
#
# It makes a difference where in the command you write this option; the linker searches and processes
# libraries and object files in the order they are specified. Thus, ‘foo.o -lz bar.o’ searches library
# ‘z’ after file foo.o but before bar.o. If bar.o refers to functions in ‘z’, those functions
# may not be loaded.
