include ITK

[Eric-JH]

Describe the bug
I used vcpkg to manage the inclusion. In the CMakeLists.txt of my project, I included ITK. But the error occured. The content of CMakeLists is same as the example given by ITK docs.

Environment

• OS: Windows 10
• Compiler: msvc 2022

Failure logs
The log was given by MSVC
CMake Error at F:/Github/vcpkg/scripts/buildsystems/vcpkg.cmake:540 (_add_executable): Target "TestDll" links to target "GTest::Main" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?

Additional context
CMakeLists.txt

If you use the itk from vcpkg, please ensure that your project contains the following:
CMakeSettings.json:

"variables": [
   {
     "name": "CMAKE_TOOLCHAIN_FILE",
     "value": "{vcpkg_path}/scripts/buildsystems/vcpkg.cmake"
   }
 ]

CMakeLists.txt:

find_package(ITK CONFIG REQUIRED)
target_link_libraries(TestDll PRIVATE ITKFFT ITKVTK ITKznz itksys)

I'm sure of my cmake-toolchain is right. And the main problem is why i can't use the example in ITK docs. I proposed the issue in ITK issues. And they thought the error was caused by vcpkg.
I understand the usage of target_link_libraries(TestDll PRIVATE ITKFFT ITKVTK ITKznz itksys). But I want a more convenient way to include, like ${g2o_LIBS} ${ceres_LIBRARIES} ${OpenCV_LIBS} so that I don't need to specify the module in CMakeLists. Now the problem is there is a similar way to include ITK according to ITK docs, but it's not feasible maybe due to vcpkg.

Thanks for pointing to the documentation. It gives another entry for #20190. It is a pity that not only the documented pattern of usage is not working, but also the vcpkg tool is promoting wrong usage patterns.
