I need help writing a makefile or a C++ binary search tree project I'm working on. The project has the following files: main.cpp, CPersonInfo.h, CPersonInfo.cpp, CBinaryNode.h, CBinaryNode.cpp, CBinaryTreeInterface.h, CBinaryNodeTree.h, CBinaryNodeTree.cpp, CBinarySearchTree.h, and CBinarySearchTree.cpp. CBinaryTreeInterface does not have a corresponding cpp file.

CBinaryNodeTree includes from CBinaryNode and CBinaryTreeInterface. CBinarySearchTree includes from CBinaryNodeTree, CBinaryNode, and CBinaryTreeInterface. Main.cpp includes from CPersonInfo and CBinarySearchTree. CBinaryNode, CBinaryTreeInterface, and CPersonInfo do not include from anything. I tried posting the whole code that I had written, but Chegg flagged it as "too long."
