Hi Claudio, It's great to see your enthusiasm about Mixxx. Working on rewriting the build system for cmake sounds like a great way to learn about Mixxx's codebase and polish your cmake skills.
Before beginning to work on a big sweeping change like this, our developers generally like to discuss the changes publicly on mixxx- devel before committing large amounts of time to them, as I'm sure is the case with other open source projects as well. We do this to help ensure that the projects undertaken by contributors are aligned with our current development goals. Currently, there were no plans to migrate our build system away from SCons to something else. Our SCons build system was written last summer (2007), when we ported from Qt 3 to Qt 4. I don't think we've seen any major complaints about SCons coming from our developers, and if we were to move to another build system, we'd need some very good reasons. That being said, I'd be more than happy to discuss SCONS and cmake with you. What are the goals you intend to achieve by moving the build system to cmake?
