Use the C/C++: Change Configuration Provider. For example, the CMake Tools extension can configure projects that use the CMake build system. Or, if you install a build system extension that interfaces with our extension, you can allow that extension to provide the configurations for you. In that view, you can change the compiler you want to emulate, the paths to include files you want to use, preprocessor definitions, and more.

If this automatic configuration is insufficient, you can modify the defaults by running the C/C++: Edit Configurations (UI) command. (for example, cl.exe/MinGW for Windows, gcc/clang for macOS/Linux). Without any configuration, the extension will attempt to locate headers by searching your workspace folder and by emulating a compiler it finds on your computer.
