You need to build PrusaSlicer by your self.

But on my PC the I have issue with cmake.

@cmguo can you provide a builded version ?

@cmguo Can you also please rebase you PR ?

Glad to see this being merged, is there intent in the future to include color data along with geometry? The primary benefit of a 3mf from other slicers is color assignments for MMU
