Hello community, I followed the download and build guideline from ebenoist on his repo [https://github.com/ebenoist/libblinkstick](https://github.com/ebenoist/libblinkstick) and I was able to download the makefiles and build it on my mac. I got the Blinkstick-CLI tool working. But, when I wanted to compile my own C file it gave me the error: “‘Blinkstick.h’ could not be found”. It’s weird because the Blinkstick-CLI tool is working which means I have all the libraries and software installed into my system. I wanted to reach out if anyone knows how I can tackle this error. - Thank you.

This is the code i am running:

```
   #include <stdio.h>
   #include <blinkstick.h>

   int main() {
       blinkstick_device* device = blinkstick_open();
       if (device == NULL) {
           printf("Failed to open BlinkStick device\n");
           return 1;
       }
       
       blinkstick_set_color(device, 255, 0, 0); // Set color to red
       usleep(1000000); // Sleep for 1 second
       blinkstick_set_color(device, 0, 0, 0); // Turn off the LED

       blinkstick_close(device);
       return 0;
   }
```
