CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION

.. versionadded:: 3.4

Visual Studio Windows Target Platform Version.

When targeting Windows 10 and above, :ref:Visual Studio Generators for VS 2015 and above support specification of a Windows SDK version:

If :variable:CMAKE_GENERATOR_PLATFORM specifies a version= field, as documented by :ref:Visual Studio Platform Selection, that SDK version is selected.
Otherwise, if the WindowsSDKVersion environment variable is set to an available SDK version, that version is selected. This is intended for use in environments established by vcvarsall.bat or similar scripts.

.. versionadded:: 3.27 This is enabled by policy :policy:CMP0149.
Otherwise, if :variable:CMAKE_SYSTEM_VERSION is set to an available SDK version, that version is selected.

.. versionchanged:: 3.27 This is disabled by policy :policy:CMP0149.
Otherwise, CMake uses the latest Windows SDK version available.

The chosen Windows target version number is provided in CMAKE_VS_WINDOWS_TARGET_PLATFORM_VERSION. If no Windows 10 SDK is available this value will be empty.

One may set a CMAKE_WINDOWS_KITS_10_DIR environment variable to an absolute path to tell CMake to look for Windows 10 SDKs in a custom location. The specified directory is expected to contain Include/10.0.* directories.
