I'm currently having issues to build V8 version 11.x on Windows, specifically every version beyond 10.0 does not build on Visual Studio 2019 (16.11.22) due to different build errors. V8 version 9.99 builds for me successfully using the steps described below.
Does V8 above version 10 still support a Visual Studio build, or has the V8 team switched to using clang on Windows entirely? Because from the build issues of the 10.x or 11.x versions I get the impression that V8 is not CI tested on Visual Studio anymore.
I'm further explaining my issues in detail on the example of V8 version 11.1.55 (f7c642b0d7).
I set my environment variables as following:
set vs2019_install=[path to your \Microsoft Visual Studio\2019\Community]
set WINDOWSSDKDIR=[path to your \Windows Kits\10]
set DEPOT_TOOLS_WIN_TOOLCHAIN=0
I invoke the build with following commands:
cd v8
git checkout 11.1.55
gclient sync
gn args out/x64.debug
ninja -C out/x64.debug v8_monolith
Following arguments are passed to gn (when the editor opens due to gn args)
is_component_build = false
is_debug = true
symbol_level = 0
target_cpu = "x64"
use_goma = false
v8_enable_backtrace = false
v8_enable_fast_mksnapshot = true
v8_enable_slow_dchecks = true
v8_optimized_debug = true
enable_iterator_debugging = true
v8_static_library = true
v8_monolithic = true
v8_use_external_startup_data = false
use_custom_libcxx = false
is_clang = false
use_lld = false
use_cxx17 = true
The first build error is:

Is V8 version 11.x still buildable using Visual Studio (2019)? Or what needs to be done to build it?
The overall build procedure described here is probably ok since v8 9.99 builds and runs without any issues using the steps above.
(V8 developer here.)
has the V8 team switched to using clang on Windows entirely?
Yes, a long time ago.
I get the impression that V8 is not CI tested on Visual Studio anymore.
That impression is incorrect, there's an MSVC builder and it is being kept happy. I'm not sure which version of Visual Studio it's using, could be 2019.
Configurations beyond the one used by this builder are community-supported. You are welcome to contribute a patch.
Side note: there is nothing special to "version 10". Release branches are created on a calendar-based schedule, and we simply use "10.0" after "9.9" (and there never was a "9.99"); see here for more.
