What do the options in make.bash mean?

[omerien]

Hello, I've been trying to add macOS install commands in make.bash so that a macOS build can be made since it compiles well using the same options as the linux version (and macOS is supported out-of-the-box according to https://gist.github.com/asukakenji/f15ba7e588ac42795f421b48b8aede63), but I've been stuck trying to understand what are the different options in the file and to what use-cases do they relate. Could you help me on that side?
