Question 1
The first image shows the toolchain configuration of my previous project, and the second image shows the configuration displayed in my newly created project. Why do I need to reinstall the toolchain when creating a new project on the same computer?
Question 2
I remember that when I first used the extension, these tools were all specified through scripts. However, after using it for a period of time, I found that CMake, programmer, and other tools could not find the specified paths, so I had to add them all to the environment variables.
