Is there a way to concatenate 2 strings literals to form an include path?

Code stub:

```
#define INCLUDE_DIR "/include"
#include INCLUDE_DIR "/dummy.h"

```

Looking at [this question](https://stackoverflow.com/questions/20524491/preprocessor-concatenation-for-include-path), the answers point in a different direction (compiler command line). It is mentioned [here](https://stackoverflow.com/a/20524959/2436175) that it is seemingly not possible, but I wonder if the topic has been dug enough.

(I do have an use case in which this is relevant, please focus your answers/comments on this question only.)
