I've got only one "unknown" - env var 3RD_PARTY_LIB_HOME. The rest is deducible.
The list of libs to link with and list of defines I know.

I don't think user-config is an option here. I need to setup my Jamfile so that
user only need to set 1 env var for it to work.

How do I list all the libraries to link with? Some static some dynamic.

Can I put this file along with my own Jamfile? How will I refer to it?

Why Can't I do a deduction in regular lib rule? in most cases it's just simple
$(HOME)/include and $(HOME)/lib
