There is no need to use target specific variables. Regular dependencies should be enough.
Unless you have some sort of specific requirements that you haven't stated, I suggest letting make do the work for you (default rules and flags).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
