记录window cmake 加载 webrtc.lib

gn gen  --ide=vs2022 --args="is_clang = true use_custom_libcxx = false use_rtti=true rtc_include_tests=false enable_iterator_debugging=true symbol_level=0 " ../out/debug_x64

ninja -C ../out/debug_x64

use_custom_libcxx = false use_custom_libcxx=false这是用来控制编译WebRtc时使用的c++库的。原因很简单，如果不加这个编译开关的话，WebRtc编译默认使用libc++来编译，而我们编译别的代码用的是libstdc++，这样在编译的过程中就会导致用到std::string的地方各种错误

rtc_include_tests=false 关闭单元测试代码，挺高速度

如果生成遇见下面的 错误

 implicit conversion changes signedness: 'size_t' (aka 'unsigned long long') to 'ptrdiff_t' (aka 'long long') [-Wsign-conversion]

修改编译文件
third_party/abseil-cpp/BUILD.gn

config("absl_default_cflags_cc") {
  #cflags_cc = [""]
  cflags_cc = ["-Wno-error"] #关闭调 警告报错
  if (is_clang) {
    cflags_cc += [
      # TODO(crbug.com/588506): Explicitly enable conversion warnings.
      "-Wbool-conversion",
      "-Wconstant-conversion",
      "-Wenum-conversion",
      "-Wint-conversion",
      "-Wliteral-conversion",
      "-Wnon-literal-null-conversion",
      "-Wnull-conversion",
      "-Wobjc-literal-conversion",
      "-Wstring-conversion",
    ]
    if (!is_nacl) {
      cflags_cc += [ "-Wbitfield-enum-conversion" ]
    }
  }
}
