Description of the bug:

Building C++ with Clang 16.0.0 and Bazel 6 on Windows spits out "missing dependency declarations" for include files:

ERROR: .../BUILD:10:10: Compiling main.cpp failed: undeclared inclusion(s) in rule '//:main':
this rule is missing dependency declarations for the following files included by 'main.cpp':
  'C:/Program Files/LLVM/lib/clang/16/include/vadefs.h'

The clang lib is installed in C:/Program Files/LLVM/lib/clang/16, but Bazel uses clang-cl -v to detect the version used in the path, which is 16.0.0 here, hence wrongfully using the C:/Program Files/LLVM/lib/clang/16.0.0 path.

In external/local_config_cc/BUILD:

cc_toolchain_config(
    name = "clang_cl_x64",
    cpu = "x64_windows",
    compiler = "clang-cl",
    # ...
    msvc_env_include = "...;C:\\Program Files\\LLVM\\lib\\clang\\16.0.0\\include",
    msvc_env_lib = "...;C:\\Program Files\\LLVM\\lib\\clang\\16.0.0\\lib\\windows",
    # ...
    cxx_builtin_include_directories = [
        # ...
        "C:\\Program Files\\LLVM\\lib\\clang\\16.0.0\\include"],
    # ...
)

What's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

Use the following C++ file

#include <stdio.h>

int main()
{
    printf("Hello, world! " __clang_version__ "\n");
    return 0;
}

With the Bazel config described in https://bazel.build/configure/windows#clang with --incompatible_enable_cc_toolchain_resolution.

Which operating system are you running Bazel on?
