1. With the editor (VSCode/Clion etc. ) Write source code , Such as main.cpp file
2. Compile the code with the compiler to generate the target file , Such as .o
3. Use linker to connect object code to generate executable , Such as Windows Under the .exe and Linux The executable under

• make

If the source file (.cpp) Too much , Compiling one by one will be particularly troublesome , So there was make Tools , It's an automated compilation tool , You can use a single command to achieve full compilation , But developers need to write a rule file ,make Batch compilation based on rule files , This file is makefile

• CMake

But for a particularly huge project , Write a makefile It's really a very complicated thing , And there it is CMake,CMake Responsible for reading all source files , And then generate it automatically makefile, But at this moment , You need a developer to write a rule file ,CMake This rule file generates makefile, This file is CMakeLists.txt

therefore , One Cpp engineering , From source to run , You can write it manually makefile file , Then compile , Generate an executable file ; You can also write CMakeLists file , adopt CMake Tools , Automatic generation makefile file , Then compile to generate an executable file
