Hi, I'm not sure I completely understand what you're trying to do, but if lack of internet access is the only problem, I think you should just be able to override the URL it tries to download by setting the ARROW_SUBSTRAIT_URL environment variable to some local file:// URL. I think it should work as long as the hash matches what Arrow's build system expects from thirdparty/versions.txt.
I'm not sure why you're not seeing the library. With `--preset ninja-debug`, I'm getting a libsubstrait.a in build/debug. I'm not familiar enough with Arrow's build system to provide more help there.
