The solution was to append -G "MinGW Makefiles" to cmake -S . -B Build command. This worked for me, you can also try to use another variants. Just write a "cmake -G" and see full list of posible variants.

Also, there is a release for now, and you dont anymore need to buld project by yourself.

I installed mingw to get mingw-make.exe, and then told cmake to use the MinGW Makefiles generator:

PS C:\Tools\alpaca\alpaca.cpp> scoop install mingw

adamjames's step helped me! if you don't have scoop yet installed, like me, call the following in Windows PowerShell

iwr -useb get.scoop.sh | iex

Such as:

PS C:\repo\AI\llm\alpaca\antimatter15\alpaca.cpp> iwr -useb get.scoop.sh | iex Initializing... Downloading ... Creating shim... Adding ~\scoop\shims to your path. Scoop was installed successfully! Type 'scoop help' for instructions.

In this case for installation you should use it in Developer Command Prompt window (Developer Command Prompt for VS 2022), you can find it in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Visual Studio 2022\Visual Studio Tools.

1. Remove old alpaca.cpp folder
2. Reinstall using Developer Command Prompt for VS 2022

It seems I didn't have Visual Studio installed. I was just following main page install instructions (github.com/antimatter15/alpaca.cpp) and they didn't mention that requirement. However, many thanks! It seems the code works after installing VS (Visual Studio).
