Trying to build quickjs on ubuntu20. Getting the following error on two different ubuntu instances.

cmake and ninja install was successful.
sudo apt install cmake ninja-build # Ubuntu

The latest version depends on rust, please make sure rust installed.

A little confused here. I compiled the original repo https://github.com/bellard/quickjs with basic cmake and gcc.
But here, the compiler detection is not using the existing compiler. Rather I should installed another compiler rustc. Is that what you recommend.

Just saw your prior commits. You have progressively moved to rustc for maintainability. Understood thanks.
