[POC|Invalid] Testing vcpkg without installed MSVC

[Neumann-A]

Hijacking x64-windows CI for this.

wished somebody would make Visual Studio truly portable. MSBuild looking up all those reg keys is a bit annoying.

No NETFXSDK installed.

Also what are all those different versions about and why don't any of those correlate to the folder version names.

Build system check:

• cmake
• autotools
• meson
• bazel
• qmake
• msbuild (needs ENV{WindowsSDKVersion} fixed) fixed it here

Already pretty good:

Fix for using the Visual Studio Generator:

a) Install /VC/Auxiliary/Build/Microsoft.VCToolsVersion.default.txt from the v143 version
b)

   set(CMAKE_GENERATOR_INSTANCE "${_VCPKG_INSTALLED_DIR}/${VCPKG_TARGET_TRIPLET}/VS/,version=17.12.35410.122" CACHE INTERNAL "")
   set(CMAKE_VS_VERSION_BUILD_NUMBER 17.12.35410.122)

c) list(APPEND CMAKE_TRY_COMPILE_PLATFORM_VARIABLES _VCPKG_INSTALLED_DIR) (for setting CMAKE_GENERATOR_INSTANCE)
d) Update CMake v3.31.0

hmm: "-DCMAKE_MAKE_PROGRAM=D:/downloads/tools/ninja/1.10.2-windows/ninja.exe"

@dg0yt: Do you have a PR fixing Bazel. I see the error in ryu here:

The target you are compiling requires Visual C++ build tools.
Bazel couldn't find a valid Visual C++ build tools installation on your machine.

Visual C++ build tools seems to be installed at D:\installed\x64-windows\share\msvc\..\..\VS\VC 
But Bazel can't find the following tools: 
    VCVARSALL.BAT, cl.exe, link.exe, lib.exe, ml64.exe 
for x64 target architecture 
 
Please check your installation following https://docs.bazel.build/versions/main/windows.html#using 

and the docs at https://bazel.build/configure/windows#using and think there is still a lot to do for correct bazel support.
