Open source C/C++ projects built with CMake (OpenCV, VTK Visualization Technology Toolkit) 
Make Cmake build a pure C language development framework in QT - detailed explanation
Project directory structure
Detailed explanation of the QT project column corresponding to the top-level CMakeLists.txt of the project

Add xc in the specified directory to compile ( lazy people only need to remember this step, no need to learn CMake )
For example, to add pwm.c of app/driver in the QT pure C project directory to compile, that is, to change the top-level CMakeLists.txt as shown in the figure below:
