@domenkozar do you think it makes sense to add support do Conan to devenv? Despite the lack of a de facto standard package management system for C++, in my opinion Conan is the one that best models the full complexity of C/C++ dependency tracking (it makes possible to take into account such subtleties as header-onliness, different libcxx ABIs, standard compatibility etc.). It's versatile, customizable, works fine with the most well tested generators out of the box with CMake-based projects.

The module I've coded into flake.parts was already designed to be easily integrated here in devenv.

The official site is: https://conan.io/
The docs: https://docs.conan.io/2/

Sounds good to me, shouldn't it be under languages.cplusplus.conan?

[tarc]

It also supports the C language as well. That's why I decided to put it under integration...

[tarc]

I'm moving it to languages.cplusplus.conan and languages.c.conan instead. You're right. It makes way more sense there.

See how we handle bun

Hello, @domenkozar . I refactored it under languages.cplusplus.conan do you mind taking a look, please?
