Help me compiling in Dev-C++

I am beginner. I work in Windows OS. I have Dev-C++ in my PC. I have some Unix like programs written on C++ (or C). I am not author these programs. Dev-C++ has all for compiling its. Other compile them for Windows. The Program Source Code has make-file for Unix and VC++. In GCC MinGW Compiler can just compile this programs. But I can't run just make file in Dev-C++.

It is necessary to create Dev-C++ project. How can just compile Unix-like program in Dev-C++? How can compile the program not written in Dev-C++ in Dev-C++?
