Building and Running your Project

Type CTRL + SHIFT + P to open a command palette, type cmake to filter and click CMake: Configure. The first time you do this it will give you the option to choose a toolchain. If your desired toolchain does not appear, choose the option to scan and it should appear.

CMake will use the first toolchain listed in your system variable path.

After choosing CMake: Configure, the project will be configured, you can then choose CMake: Build to build the project.

If you wish to change any settings after a complete build, you need to either use the option CMake: Delete Cache and Reconfigure, or delete the "build" folder.
