Executables: applications

This folder contains implementation files and CMake files that build executable files.

Temporary build files, compiled libraries and executables: build & build-arm

These to folders are used by the build system to build everything.

CMake scripts and Toolchain files: cmake

This folder contains the installation script for Google Test, and the Toolchain file that defines the compile options for building code for the ZYBO.

Utility Scripts: scripts

Currently, there is one script that copies all ARMv7 executables and libraries from the Docker toolchain and OpenCV builds, and stores them in a filesystem in a file that can be copied to the SD card. These libraries are needed to run the compiled code.

Documentation: doc

This folder contains documentation in the form of MarkDown documents, as well as a recipe for automatically generated documentation using Doxygen.
The output of Doxygen is in the html subfolder: use index.html as the entry point.

Docker build instructions: docker

This folder contains all files to build the Docker images with the toolchain and necessary libraries.

Source files: src

This folder contains the source code for the different libraries.
The code is split up in "modules". Each of these modules has a specific task and has a number of tests.

A module folder consists of three main folders and a CMake file:

• src
  This folder contains all implementation files and private headers. They are necessary for building the library itself, but you don't need them when using the library.
• include
  This folder contains all public headers. They define the public API of the library, and are needed when using the library.
• test
  This folder contains the unit tests for the library functions.
• CMakeLists.txt
  This file defines how the library should be compiled.
