Reasses building under WSL

[mribbons]

manual libuv build is now possible, we just need to extract the necessary options from libuv's generated .vsproj and pass those th clang.

I can't recall if there were other blockers.

• Test MSVC clang/++ from WSL
• Test ssc build with prebuilt libuv
• Test android builds

IIRC, I believe you can run software compiled for Windows in WSL, but you cannot run software compiled in WSL for Windows. We'll need to cross compile for Windows in WSL

It looks like that project is still using MSVC and Windows SDK, that's what I had in mind :)

This came up after building from a WSL path mapped to a network drive. The same will occur within WSL:

U:/home/test/socket/build/include\WebView2ExperimentalEnvironmentOptions.h:12:10: fatal error:
      'webview2experimental.h' file not found
#include "webview2experimental.h"

hack:

cp build/include/WebView2.h build/include/webview2.h
cp build/include/WebView2Experimental.h build/include/webview2experimental.h

To resolve we would need to request MS to fix the headers, or patch them after extracting.
