WinForms native tests are not building in VMR

[NikolaMilosavljevic]

The build is failing with the following issue (dotnet/sdk#44843 (comment)):

The command "
      call "D:\a\_work\1\vmr\src\winforms\eng\init-vs-env.cmd" 
      
       cmake -G "Visual Studio 17 2022" -A Win32 -B "D:\a\_work\1\vmr\src\winforms\artifacts\obj\NativeTests\x86\Release" -S "D:\a\_work\1\vmr\src\winforms\src\System.Windows.Forms\tests\InteropTests\NativeTests" -DCMAKE_INSTALL_PREFIX=D:\a\_work\1\vmr\src\winforms\artifacts\bin\NativeTests\x86\Release --log-level=WARNING
      " exited with code 1.

I've opted out of building tests in this repo with dotnet/sdk#44843

With #13187 and dotnet/sdk#47870, all other winforms tests are now enabled in VMR.

If it's just the native tests that aren't building in VMR, we don't believe there is high risk to the project. We'll mark this for future and try to get to it.

when I run

cmake -G "Visual Studio 17 2022" -A Win32 -B "Q:\winforms\artifacts\obj\NativeTests\x86\Debug" -S "Q:\winforms\src\test\unit\interop\NativeTests" -DCMAKE_INSTALL_PREFIX=Q:\winforms\artifacts\bin\NativeTests\x86\Debug --log-level=WARNING

locally, I get

CMake Error at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

my cmake version is the latest

Q:\winforms>cmake --version
cmake version 4.0.1

I suggest updating cmakelists.txt to the oldest version that is compatible with the latest one, i.e. the oldest one that builds by v4.0.1

- cmake_minimum_required (VERSION 2.8.12)
+ cmake_minimum_required (VERSION 3.10)
project (NativeTests)

VS from main has cmake recent enough -
C:\Program Files\Microsoft Visual Studio\2022\Main>Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe --version
cmake version 3.30.5-msvc23

VS from the preview channel (used by the VMR) has the same version

C:\Program Files\Microsoft Visual Studio\2022\Stable>Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe --version
cmake version 3.30.5-msvc23
