Related to prebuilt openconnect

By default, we use the prebuilt openconnect static lib, which is downloaded from sourceforge.

If you want to build the openconnect static lib when building the crate, you can add environment variable to your .cargo/config file.

[env]
OPENCONNECT_USE_PREBUILT = "false"
