coin-or/Clp ? reverse-engineered prompt

Build me the Clp linear programming solver so I can use it both as a library and as a simple command line tool.

I want it to solve optimization problems where it minimizes a linear objective with variable bounds and matrix constraints, and it should support both primal and dual simplex, plus the barrier method. It should be able to read a problem file, run presolve, and let me switch between primal and dual from the command line. Please make it build cleanly from source, include the usual test run, and keep it usable on Linux and Windows if possible.

If there are any missing setup details or current build instructions that would help, look them up online and follow the project docs. Also make sure the basic executable gives helpful hints when run with no arguments, so it feels usable right away.
