CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION_MAXIMUM does not affect VisualStudio 15 2017 project files

I'm trying to set Windows sdk version to an appropriate value in the following environment:

• OS: Windows 10.0
• CMake version: 3.19.3
• Generator: Visual Studio 15 2017 Win64
• Installed SDK-s: 10.0.10240.0, 10.0.10586.0, 10.0.14393.0, 10.0.15063.0, 10.0.16299.0, 10.0.17134.0, 10.0.17763.0

I have set CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION_MAXIMUM before the first call of project() to 10.0.17134.0 but it does not have any effect, the used version is always the most recent one: 10.0.17763.0.

I have checked the cmGlobalVisualStudio14Generator and the cmGlobalVisualStudioVersionedGenerator classes and disovered the following behavior:

• the main part of the logic finding the required windows SDK version is here cmGlobalVisualStudio14Generator::GetWindows10SDKVersion
• at some point this calls std::string maxVersion = this->GetWindows10SDKMaxVersion(mf);
• implementation of GetWindows10SDKMaxVersion has a non-dummy implementation in cmGlobalVisualStudio14Generator...
• ...but it is overridden in cmGlobalVisualStudioVersionedGenerator and that returns an empty string
• thus the cmGlobalVisualStudio14Generator::GetWindows10SDKVersion function does not remove available SDK versions above the requried maximum.

Is that the required behavior? If so, how can I select a Windows SDK in the formerly mentioned environment?

If I remove the overriden dummy behavior of GetWindows10SDKMaxVersion from cmGlobalVisualStudioVersionedGenerator everything works well in my environment.

The behavior was the same with cmake-3.14, but I did not check the code.
