Did you already look in the documentation?

There are examples there too.

For a union, it is not possible to do 7 boxes in one call. The most
straightforward way is to do 6 calls (first 1 and 2, then result with 3,
then result with 4, etc)

A makefile is not provided and not necessary, the library is header-only.
