I used  
CMAKE 3.19.8  
Visual Studio 2019 x64 tool v142  
And refer to

> I hope I might find some help here. I recently started working on the PkModeling extension an I am trying to get it to build on various continuous integration platforms (Appveyor for Win and Travis CI for Linux and Mac). [https://github.com/michaelschwier/PkModeling/tree/CI](https://github.com/michaelschwier/PkModeling/tree/CI) I got the build working on Appveyor but it copies some of the generated files to the wrong output. So the expected output would be “[pkmodeling-build]/bin/Release” (expected files there are: PkModeling.exe, PkModelingLib.dll…

I first installed and compiled  
ITK DCMTK SlicerExecutionModel ZLIB  
And join them in CMAKE-GUI  
The following is my CMAKE interface

I used the Release mode to build  
Then here is my error list

I want to know what I should do to successfully build Slicer  
Thank you for your patience to read this

You previously posted on the following thread. Did the solution provided there solve the issue?

> [@Build Slicer failed on win10](https://discourse.slicer.org/t/build-slicer-failed-on-win10/15674/6):

> Probably the issue is that your system code page is set to 950 (Traditional Chinese) and c:\S4R\LibArchive\libarchive\archive\_read\_support\_format\_rar5.c contains characters that cannot be interpreted in this code page. The simplest is to remove the offending characters (remove entire line 74, it is just a comment): \* "Rar!→•☺·\x00" If you will keep running into similar errors then you may consider switching to Latin1 code page for the build.

I do see in one of the logs you posted that it warns the following:

> warning C4819: The file contains a character that cannot be represented in the current code page (950)

Sorry this is my fault. I emptied the old folder before this construction, which caused the same error to reappear. I have fixed it, thank you  
This is the file I rebuilt, and the error is reduced to 9

A workaround is to temporarily rename your other Python installation folder (anaconda, etc.). You can rename it back to the original name after Slicer build is complete.

I tried the method you recommended, and successfully built the Release and Debug of Slicer. Thank you for your answers!
