Create a set of key-value pairs that can be converted into a Zig source file and then inserted into a Zig compilation's module table for importing.
This provides a way to expose build.zig values to Zig source code with
@import. Related: Module.addOptions.
pub fn addOptions(b: *Build) *Step.Options
pub fn addOptions(b: *Build) *Step.Options {
return Step.Options.create(b);
