+ 1. Those set on the current target (not in a config). |
+ 2. Those set on the "configs" on the target in order that the |
+ configs appear in the list. |
+ 3. Those set on the "all_dependent_configs" on the target in order |

+ 4. Those set on the "public_configs" on the target in order that |
+ those configs appear in the list. |
+ 5. all_dependent_configs pulled from dependencies, in the order of |

+ more than once, only the first occurance will be used. |
+ 6. public_configs pulled from dependencies, in the order of the |
+ "deps" list. If a dependency is public, they will be applied |
