PlatformIO Arduino Uno library issue

[Djeunut]

I am making a project for school on an Arduino Uno.

We have to use some libraries that the teacher gave us and make some ourself.

I included them in my project and keep getting the same error.
When I make a new empty project and include the libraries there they are found immediately.
 

Does anyone know why this happens?

In the warnings on the first image, it looks like the C/C++ extension doesn't know what compiler to use.

 

Hold Ctrl + P and type "Select IntelliSense Configuration" it should bring up a menu of compilers, select one and it should be able to locate your header files.

It didn't give me any compilers to select.

There are no compiler options in the list above? Assuming they are building without issue, do any other projects you have open have a compiler selected or options available if you run the same command? You can always manually select a compiler using that UI.
