CMake build errors?

I am running into errors:

Fetching gtest...
CMake Warning (dev) at /opt/homebrew/Cellar/cmake/3.30.3/share/cmake/Modules/FetchContent.cmake:1953 (message):
Calling FetchContent_Populate(gtest) is deprecated, call
FetchContent_MakeAvailable(gtest) instead. Policy CMP0169 can be set to
OLD to allow FetchContent_Populate(gtest) to be called directly for now,
but the ability to call it with declared details will be removed completely
in a future version.
Call Stack (most recent call first):
cmake/utils.cmake:31 (FetchContent_Populate)
cmake/gtest.cmake:27 (FetchContent_MakeAvailableWithArgs)
CMakeLists.txt:151 (include)
This warning is for project developers. Use -Wno-dev to suppress it.

CMake Error: Error: generator : Unix Makefiles
Does not match the generator used previously: Ninja
Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.

Do you guys get this same error when running './x.py build'?

As the error states, you need to build in a new directory if the generator is changed.
Or you can delete the current build dir.

Oh icic, I didn't know to delete the current build. Thank you!
