Need a way to provide system defines and system includes when compiler querying is disabled (with compilerPath of "").

It's possible to disable compiler querying (and disable fallback to a different compiler on failure) by specifying a compilerPath of "". This also works in combination with a custom configuration provider or compile_commands.json, to prevent use of the compiler they indicate (in case it's not cl.exe, gcc, or a gcc variant we can query). However, the defines and includes from c_cpp_properties.json are not currently getting merged into the configuration in those cases. Since no compiler will be queried, it seems necessary to support a way for the user to provide the missing system includes and systems defines.

This issue tracks merging in the includes and defines from c_cpp_properties.json when a compilerPath of "" is used in combination with a custom configuration provider or compile_commands.json.

Suivre la manière dont c_cpp_properties.json est fusionné lorsque compilerPath est vide et qu’un fournisseur de configuration personnalisé ou compile_commands.json fournit la configuration. Vérifier le comportement avec des configurations pour lesquelles l’interrogation du compilateur est désactivée, puis s’assurer que les includes système et les defines fournis par l’utilisateur sont présents sans interroger de compilateur.
