Linguist not ignoring vendor files even after setting .gitattributes

I have a repository of my college project in OpenGL and I’m using external libraries for image loading and maths written in c. My project is written in C++ and I have set up the gitattributes files properly as described in the docs yet the libraries are not ignored in linguist.

My Repository: https://github.com/CaptainDynamight/Project-Meteora

gitattributes file : https://github.com/CaptainDynamight/Project-Meteora/blob/master/.gitattributes

Hi @captaindynamight,

Thanks for being here! I’m unable to see your .gitattributes file. If is on a private repo could you please write directly to support for assistance. If you haven’t already, please contact us at https://github.com/contact with the info, so we can look into that further.

Extremely sorry for the removal of the file. I have reuploaded the file yet the issue still exists
