 - `build_by_default` causes, when set to true, to have this target be built by default, that is, when invoking plain `ninja`, the default value is true for all built target types, since 0.38.0
 - `override_options` takes an array of strings in the same format as `project`'s `default_options` overriding the values of these options for this target only, since 0.40.0

+- `implib` when set to true, an import library is generated for the executable (the name of the import library is based on *exe_name*).  Alternatively, when set to a string, that gives the base name for the import library.  The import library is used when the returned build target object appears in `link_with:` elsewhere.  Only has any effect on platforms where that is meaningful (e.g. Windows).  Since 0.42.0
 
 The list of `sources`, `objects`, and `dependencies` is always flattened, which means you can freely nest and add lists while creating the final list. As a corollary, the best way to handle a 'disabled dependency' is by assigning an empty list `[]` to it and passing it like any other dependency to the `dependencies:` keyword argument.
