Build Error Using Atmospheric Glasses SDK <duplicate symbol>

I used the atmospheric glasses SDK, but when I tried to build the official sample source, the following error occurred and I couldn't solve it.

https://github.com/FUNIKImegane/FunikiSDK

I understand that a variable with the same name is defined in another code, but
I don't know how to deal with it and I don't have much information.

Please let me know if you know.
