### `build target` object
A build target is either an [executable](#executable), [shared](#shared_library) or [static library](#static_library).
- `extract_objects()` returns an opaque value representing the generated object files of arguments, usually used to take single object files and link them to unit tests or to compile some source files with custom flags. To use the object file(s) in another build target, use the `objects:` keyword argument.
- `extract_all_objects()` is same as above but returns all object files generated by this target
- `private_dir_include()` returns a opaque value that works like `include_directories` but points to the private directory of this target, usually only needed if an another target needs to access some generated internal headers of this target
- `full_path()` returns a full path pointing to the result target file
