Hi,  
I followed the Build Instructions to build Slicer on Windows 11.  
CMake: 3.31.6  
Git: 2.48.1  
Qt: 5.15.2 64-bit (MSVC 2019)  
Visual Studio 2022 C++ x64  
After build Slicer in Visual Studio, 10 errors occurred.

 ![Capture d'écran 2025-03-26 135231](https://us1.discourse-cdn.com/flex002/uploads/slicer/original/3X/2/9/2989aa3e1b50bd62a5da68d0e475e8fad93f670b.png)

How to solve these errors please? Thanks!

This seems to be an ITK error:

Probably you can fix it by upgrading or downgrading your Windows SDK or compiler today; or applying one of the workarounds described in the referenced issue.

This PR aims to update the Slicer ITK version to one that includes a fix for that reported ITK issue:

> <https://github.com/Slicer/Slicer/pull/8339>
>
> This updates ITK from a version based on 5.4.0 to now being based on the 5.4.3 r…elease. 
> 
> This should address build issues such as the one mentioned at https://discourse.slicer.org/t/slicer-build-failed/42319 as this now includes the https://github.com/InsightSoftwareConsortium/ITK/commit/6025654de3d815b131cebe969655c7173a27756c fix along with other various fixes included with the recent ITK patch releases on the 5.4.x release branch.
