The error is self-explaining:

An old version of CMake is being used that cannot automatically detect compiler attributes. Compiler identification is being bypassed. Some values may be wrong or missing. Update to CMake 3.19 or newer to use CMake's built-in compiler identification.

Normally, cmake is automatically installed by flutter/Android toolchain. But something prevents it from working correctly. The actual cause may vary and I'm not sure what causes the issue on your environment.

So, anyway, could you please do the following things:

• update your Android Studio
• flutter clean

Here is my Android Studio version, I don't think it needs an update.

After using cmake: 3.22.1 and ndk: 26.2.11394342 also enable Windows' Developer mode, I get the following errors

I tried it a few more times without changing anything and suddenly it worked...

Yes, so I don't know the actual cause... Need reboot or such?

[Dabbit-Chan]

I think a new version of ndk and cmake and enable developer mode will solve the problem. No need for reboot.
