Issues with following instructions building Skia

[Kalen White]

I synced build deps which successfully got everything in third_party, including libjpeg-turbo

python3 tools/git-sync-deps <- runs fine.

When I build it does not find the jpeg headers:

    #include "jpeglib.h"

Its in third_party & externals.  It fetched it fine.  It must be my M2 mac architecture skipping it from being included without error.  Its not including the jpeg headers there.  Something in GN must be skipping it.

Can someone inform me of a very plain set of args for building for:

Vulkan & TTF Fonts and absolutely NOTHING else?  No system font manager or anything my apps always just have a set of .ttf.  In my case I need vulkan, fonts, and thats it.

The script I got them from (canvaskit/compile.sh) had some stale properties such as skia_use_system_libjpeg_turbo, skia_use_system_libwebp.  I thought I would report that

This is m112 branch

When you disable jpeg, it still builds the jpeg tests in ganesh.
