It is still not clear to me what path we should take. Pixi is becoming more common on Linux compilation too, and seems to be better supported than the traditional LibPack. Since the former offers a programmatic, more flexible approach to packages installation, why not ditching LibPack entirely to focus support on Pixi?

I only maintain the LibPack so we can test the newest versions of these libraries -- so I will update it when I have time, but I don't consider it a "normal" way of building FreeCAD anymore.

Can't that be accomplished by Pixi too?

[stefano2734]

It is ok too close here development, when PIXI is here the new base.
But then some comments in readme.md should be done about this.
