Compilation Error: "Unresolved reference: lenssdkverify"

[gongzhimin]

Hello authors,
When I compiling the Android code in this repo, the following error occurs: "Unresolved reference: lenssdkverify". According to the README, this project requires a Truepic C2PA verification library.

It would be greatly appreciated if the following queries could be addressed:

• Firstly, I am curious as to why this library is not present in the repository.
• Secondly, I am wondering if this library has any associated costs or if it is provided free of charge.
• Lastly, I would be grateful if you could let me know if there are any alternative options available.

Thank you very much for your attention. Any help or pointers would be greatly appreciated. 🙏
