Use cdylib for compiling plugin dynamic libraries

[Boscop]

You'd probably want to use cdylib for compiling plugin dynamic libraries here.

https://doc.rust-lang.org/reference/linkage.html

We are also using cdylib when building VST plugins in Rust.

The resulting file with cdylib will be much smaller, too.

Thanks for the idea! What’s the most benefit from using cdylib btw?

[Boscop]

Just that it's the "right thing" to use when you're not linking the lib with more Rust libs as part of a compilation pipeline. But also that the file will be smaller :)
