Rake to build a C application

Question

I'm attempting to migrate a C application I have been working on to use Rake insead of GNU Make. The file tree is something like:

project
├── LICENSE.md
├── Makefile
├── Rakefile
├── README.md
└── src
    ├── debug.h
    ├── main.c
    ├── queue.c
    ├── queue.h
    └── ui
        ├── ui.c
        └── ui.h

I want to build each file in a separate build directory and generate the dependencies of each .c file with either gcc or clang in a deps directory.

I cannot seem to find any examples of how to write a Rakefile to compile a C project. Does anyone have a link or some advice to help me get started?

EDIT: I have a temporary Rakefile that accomplishes some of the tasks I want it to eventually do. I would like to detect if clang is installed and use clang or gcc.

Here is my current Rakefile https://github.com/Rostepher/spoticli/blob/master/Rakefile

Use Ceedling!

https://github.com/ThrowTheSwitch/Ceedling

It's an automated unit test framework for C, but does a great job of simply building as well. You should be able to get what your looking for by editing a YAML config file, and you'll get Rake tasks for building out-of-the box. Of course you can create your own custom Rake tasks as well.

As a bonus you can create mocks with CMock and automated unit tests with Unity.

It's super easy to install from a gem:

> gem install ceedling
