OS: Windows.10  
Cmake version 3.22.2  
VStudio version: 17.0.5 2022  
Python 3:10 (64-bit)

hello there,  
I tried to build the SlicerCustomAppTemplate as it is as steps say in [https://www.kitware.com/slicercat-creating-custom-applications-based-on-3d-slicer/](https://www.kitware.com/slicercat-creating-custom-applications-based-on-3d-slicer/) and I get so many “Failed” and errors …

Slicer version I installed in my pc is 4.11 and the version I built (according to [Windows — 3D Slicer documentation](https://slicer.readthedocs.io/en/latest/developer_guide/build_instructions/windows.html)) is 4.13, will that gonna cause me a problem in any way?

I get this warning in CMake:

```auto
> CMake Warning (dev) at G:/W/SR/slicersources-src/CMake/SlicerMacroExtractRepositoryInfo.cmake:87 (message):

> G:/W/SR/slicersources-src/CMakeLists.txt:332 (include)
> This warning is for project developers. Use -Wno-dev to suppress it.

```

and first error was:

Did you just download the SlicerCustomAppTemplate code as zip and uncompressed? In that case you should do a proper Git clone instead.

No, I followed the instructions in “BUILD.md” file in VSCode editor after executing the two lines code in Step1 here [https://www.kitware.com/slicercat-creating-custom-applications-based-on-3d-slicer/](https://www.kitware.com/slicercat-creating-custom-applications-based-on-3d-slicer/) so I can be able to have a Cmakelists.txt file for the build!

OK thanks! The errors also suggest that the script was not able to access github (`fatal: unable to access 'https://github.com/commontk/bzip2.git/': Could not resolve host: github.com`). Either a momentary issue on the server or your own internet connection. Maybe firewall issues but I never had that with github connections. I suggest trying again until this specific error is gone and it either succeeds or another type of error happens.
