Make CI faster / enable build cache #10
Description
Currently, we are not doing cross compilation but simply compile modules in each platform target. That makes the docker build extremely slow. One of the reasons why I am not doing / cannot do the cross compilation right now is dues to rust-lang/rust-bindgen#1229 since the Rust SDK relies on the C header generated via bindgen.
There's two dimensions we can optimize regarding the CI
- Workaround the bindgen issue and do the cross compilation on the host machine. Makes build faster #12
- Enable the build cache
