iOS issue: no such subcommand: `lipo`

When I build Blokada for iOS, I see this error:

no such subcommand: lipo

On Mac OX Big Sur (11.2.1) I have it installed here:

bash-3.2$ which lipo

I see this issue when I select either Scheme: IOS, IOSNetworkExtension and Blocka Engine.

Any ideas? Thanks!

Try cargo install cargo-lipo

Thanks @Karol. I have now installed cargo-lipo and I get more errors:

= note: ld: library not found for -lSystem
clang: error: linker command failed with exit code 1 (use -v to see invocation)

error: aborting due to previous error
error: linking with `cc` failed: exit code: 1

Any ideas?

I also see that building IOSNetworkExtension results in:

library not found for -lengine

No idea what this is about.
