Describe the bug When trying to build to windows I am getting the following error

Launching lib\main.dart on Windows in debug mode... windows/flutter/CMakeLists.txt does not use FLUTTER_TARGET_PLATFORM, updating. CMake Deprecation Warning at CMakeLists.txt:4 (cmake_minimum_required): Compatibility with CMake < 3.5 will be removed from a future version of CMake.

Update the VERSION argument value or use a ... suffix to tell CMake that the project does not need compatibility with older versions.

CMake Warning (dev) at C:/Program Files/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.27/Modules/ExternalProject.cmake:3136 (message): The DOWNLOAD_EXTRACT_TIMESTAMP option was not given and policy CMP0135 is not set. The policy's OLD behavior will be used. When using a URL download, the timestamps of extracted files should preferably be that of the time of extraction, otherwise code that depends on the extracted contents might not be rebuilt if the URL changes. The OLD behavior preserves the timestamps from the archive instead, but this is usually not what you want. Update your project to the NEW behavior or specify the DOWNLOAD_EXTRACT_TIMESTAMP option with a value of true to avoid this robustness issue. Call Stack (most recent call first): C:/Program Files/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.27/Modules/ExternalProject.cmake:4345 (_ep_add_download_command) CMakeLists.txt:9 (ExternalProject_Add) This warning is for project developers. Use -Wno-dev to suppress it.
