Description of the HelloDavinci File

The samples directory contains compilation configurations and program samples (HelloDavinci included) of the Atlas. To run the HelloDavinci code file independently, obtain the Samples/Cmake, Samples/Common, and Samples/HelloDavinci folders, as shown in Figure 1.

• CMake: Stores the CMake configuration file.
• Common: Stores common code.
• HelloDavinci: Indicates the HelloDavinci project directory, including the .build file, source code file, graph configuration file, and README.md.
  

  Retain the relative paths of the three folders.
