I am not sude how vscode uses intellisense c++ settings tho, at first it seemed like it's somehow connected to makefile but... it has it's own .vscode settings so
— Tried adding includes like that, intellisense still broken
— K this maybe works
— Why would you even try this when there's nice Qt Creator?
— Cause i want to use vscode
— Only thing i want to use qt creator for is designer
— It's a bad idea
— Why lol
— Because you can't even setup this while in Qt Creator it works right out of the box
