Implementation of HOG Algorithm in C with CMake build system.

This git provides an implementaion of HOG algorithm in C found here: http://www.openpr.org.cn/index.php/Code-of-Individual-Algorithms/9-Histograms-of-Oriented-Gradients-HOG-Feature-Extraction/View-details.html

However, the above fails to compile when running make which I rectified using CMake.
