linking existed c++ static libaray in Bazel failed

Question

I am writing a OpenGL programe on windows.

I want to link precompiled GLEW32.lib, but failed and failed for a couple of hours.

In WORKSPACE, a http_archive uses to download GLEW32.lib

http_archive(
  name = "glew",
  build_file = "@//:thirdparty/glew.BUILD",
  sha256 = "ea6b14a1c6c968d0034e61ff6cb242cff2ce0ede79267a0f2b47b1b0b652c164",
  strip_prefix = "glew-2.2.0",
  urls = ["https://github.com/nigels-com/glew/releases/download/glew-2.2.0/glew-2.2.0-win32.zip"],
)

GLEW.BUILD as follow

package(default_visibility=["//visibility:public"])
load("@rules_cc//cc:defs.bzl", "cc_binary")

cc_import(
  name = "glew_lib",
  static_library = "lib/Release/x64/glew32s.lib",
  hdrs = glob([
    "include/GL/*.h"
  ]),
)

cc_library(
  name = "glew"
  includes = ["include"],
  deps = ["glew_lib"]
)

Depending binary as follow

cc_binary(
  name = "window",
  srcs = [
    "window.cc",
  ],
  deps = [
    "//engine:debug",
    "//engine:gl",
    "//playground:playground",
    "@fmt",
    "@glew",
    "@glfw",
    "@glm",
    "@imgui",
  ],
  linkstatic = 1
)

The link param file C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.32.31326\bin\HostX64\x64\link.exe @bazel-out/x64_windows-fastbuild/bin/playground/window.exe-2.params 's GLEW lib is odd. I don't know how external/glew/lib/Release/x64/glew32s.lib is generated. But GLEW.lib hadn't join linking.

Could someone help me to link existed GLEW32.lib success? Thanks a lot.

My fault. This is not bazel's issue or glew's issue. GLEW means The OpenGL Extension Wrangler Library. It doesn't contain the origin OpenGL function implements.

After adding linkopts = ["-DEFAULTLIB:opengl32.lib"] to glew cc_library. Every is OK.

The link error as follow. They are all original OpenGL functions.
