After cloning the tfhe-rs.On building i find the following error. What can i do to have it run without issues?

PS C:\Users\1012 G2\Desktop\zamadocuments\tfhe-rs> cargo run --release

Hello !
tfhe-rs is a library and is not meant to be run as a standalone program. What you are trying to run here is a helper tool used in our CI.

To use tfhe-rs you must add it as a dependency in your project. You can find more information here: Installation | TFHE-rs.

If you just want to run an example to see it in action you can use cargo run --example:
cargo run --release --features integer,internal-keycache,x86_64 --example dark_market -- fhe-improved

Please note that the cuda backend is not supported on native windows, so you should add the dependency without the gpu feature or run it under WSL.
