Describe the problem
Hello Meshroom team,

I have an issue when trying to launch Meshroom 2025.1.0 on my Linux Mint 22.2 machine. After extracting the Meshroom 2025.1.0 binary and attempting to run it:

<Path>/Meshroom-2025.1.0$ ./Meshroom

I receive the following error:

qt.qpa.plugin: From 6.5.0, xcb-cursor0 or libxcb-cursor0 is needed to load the Qt xcb platform plugin.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: linuxfb, xcb, vnc, eglfs, offscreen, wayland, vkkhrdisplay, minimalegl, wayland-egl, minimal.

Are additional dependencies required?

Thanks for your effort!
