Switch from Linux to Windows with Qt6, CMake build system result in linkage error for __imp_glDrawArray

Hi dear Qt users!
I usually work on Linux, and everything is perfect. But, I also need to compile my project on Windows. Currently, using Visual Studio 2022, and Qt6.8, Vulkan SDK is also installed.

I'm using CMake, my CMakeLists.txt is looking like

cmake_minimum_required(VERSION 3.16)
project(Test LANGUAGES CXX)

SET(CMAKE_MODULE_PATH ${Test_SOURCE_DIR}/cmake)

find_package(Eigen3 REQUIRED)
include_directories( SYSTEM ${EIGEN3_INCLUDE_DIR} )

set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTOUIC ON)

find_package(Qt6 REQUIRED COMPONENTS Widgets OpenGL OpenGLWidgets)
add_executable(Test
   main.cpp
   MyCustomTestWidget.cpp
   )
target_link_libraries(Test PRIVATE Qt6::Widgets Qt6::OpenGL Qt6::OpenGLWidgets)
target_compile_features(Test  PRIVATE cxx_std_17)

After setting some CMake variable (Qt6_DIR, Qt6CoreTools_DIR and QT6GuiTools_DIR), project is generated as it should with MSVC x64 compiler. However, compilation fails at linking indicating __imp_glDrawArrays is missing.
Does someone have a solution for this?

Thank you for reading

Try to link against the opengl libs (opengl32 as you can see in https://learn.microsoft.com/en-us/windows/win32/opengl/gldrawarrays )

Thank you @Christian-Ehrlicher it worked!
Could it be considered as a bug? (I would expect the cmake files of Qt to link openGL as I'm using Qt6::OpenGL)
