Intellisense: Can't resolve identifiers from include path #10520
Description
I am using VSCode on a Mac with the Arduino plugin. I have configured intellisense with a c_cpp_properties.json to include necessary header files. The Problems pane shows lots of unresolved identifiers. It doesn't show any issues with the included header files. If I open a header file that is in the include path in VSCode that defines one of the unresolved identifiers, that particular unresolved identifier goes away.
In the attached screenshot, CanHacker was an unresolved identifier until I actually opened the file in VSCode.
