Storing version in WebAssembly application

Question

I've got REST service written in C++/Qt 5.15.x. Under some URL REST service sends WASM stuff. It's a GUI application (REST client) written in C++/Qt 5.15.x. It is possible to embed some function which shows version etc? I'd like to load wasm on the server side (Debian) in "bla-bla.wasm --version" style. Or call some function from wasm via native REST service.

In fact, REST service detects wasm renewal on the server side and will notify clients about new version via WebSocket.

I am using for similar purpose git describe sent through Makefile as compilation definition.

In C++ there is a function which reads and parses string initialized with definition from Makefile (using as an input mentioned git output).

Makefile VERSION="-DVERSION_NUMBER=\"$(shell git describe)\""

C++ std::string version(VERSION_NUMBER);
