# "make" works based on whether it is compiled or not, but a make clean can sometimes make it seem like
# there is a relink or no recompilation messages appear, such as from libft. This is for aesthetic reasons,
# as I base it on the ".a" files, and it does not affect the compilation, program operation, or relinks.

# Running  "make cb" causes relink because it attempts to overwrite files, thus generating relink to switch
# between <normal mode> and <color bleeding mode>.

# Remove the "-O3" flag during correction, as it fixes possible errors but greatly improves performance!

# If “makefile.gen” does not exist and you try to run “make fclean” (for example, immediately after downloading
# the repository), the makefile will return an error due to the absence of this mlx file. This is due to the
# different systems on which mlx has been used. It is not an error!
