Add build script for Microsoft Visual Studio

[PeterReid]

For Windows users, this batch file builds sd.exe using Visual Studio's cl.exe. Most of the file is dedicated to checking the environment and reporting errors nicely. Specifically, it will explain what to do if cl.exe is missing or for the wrong architecture.

Thanks for your contribution. However, I believe CMake works well as a build tool on Windows. For instance, it automatically detects the compiler, eliminating the need to open the Developer CMD or add the cl.exe directory to the PATH. It can define macros through command-line parameters to utilize certain GGML features, such as OPENBLAS. Additionally, GGML's CMake files have pre-defined macros and compiler parameters, including those related to AVX. Achieving a similar effect through a build script would require a significant amount of work.

Thanks for this. I don't have CMAKE on my computer, so I'll be using this script instead.

iirc, visual studio ships with cmake and ninja. are you on some very old version?

How to get cmake to produce the optimal compiler options? I've not been sufficiently motivated to learn cmake, yet.

As for Visual Studio - I like to use \GL:

cl.exe /arch:AVX2 /fp:fast /Ox /EHsc /GL /I. /I ggml\include\ggml /I ggml\include examples\main.cpp stable-diffusion.cpp ggml\src\ggml.c /link /out:build\sd.vs.exe

... and for clang, I do:

clang.exe -march=native -ffast-math -O3 -fno-exceptions -flto -I. -Iggml/include/ggml -Iggml/include examples/main.cpp stable-diffusion.cpp ggml/src/ggml.c -fuse-ld=lld -o build/sd.clang.exe
