    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 C:\Program Files\Microsoft Visual Studio\2022\Enterprise\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://bazel.build/docs/windows#using
