Fails to build on Windows

[davispuh]

How are you supposed to build dstep on Windows?

I installed:

1. DMD 2.112.0 (dmd-2.112.0.exe) from https://dlang.org/download.html#dmd
2. Visual Studio Build Tools 2019 (DMD installation offered, selected Build Tools instead of full VS)
3. Git (Git-2.54.0-64-bit.exe)
4. LLVM 22.1.8 (LLVM-22.1.8-win64.exe) from https://github.com/llvm/llvm-project/releases/

Then opened D2 64-bit Command Prompt and:

C:\> git clone https://github.com/jacob-carlborg/dstep.git
C:\> cd dstep
C:\dstep> dub build --arch=x86_64

I look at C:\LLVM\lib and indeed there is no clang.dll but there is libclang.lib. And there is libclang.dll in C:\LLVM\bin.
So I apply patch:

Okay so the generated flags have wrong syntax and not how this DMD/LLVM linker wants it.
I apply patch:

There's been a few years since I worked on DStep. According to CI, the latest version of LLVM that has been tested is LLVM 15.0.7. The configure script was originally created only for Posix platforms. I don't recall if it supposed to work on Windows or not. I would suggest looking at the CI setup. But I've noticed that the CI workflow has regressed as well. It needs to be fixed to be able to verify your pull requests.
