I've a little problem, I'm trying to create a library with processor variables for tune it.

So in `.ino` I declared my preprocessor var, but preprocessor variables appear not defined in my library. (Notice that I've create a folder `test/test.h` in `libraries` directory of Arduino IDE)

Some code to reproduce the problem : 

**test.ino** : 

```
#define TEST

#include "test.h"

void setup() {}
void loop() {}

```

**test.h** (edited, reverse error message, this is solution) 

```
#if defined(TEST)
  #error "DEFINED"
#else
  #error "NOT DEFINED"
#endif

```

If I compile it, I fall on `#error "NOT DEFINED"`. 

Somebody with an idea ?

Have a good day
