This fix warning in build stage:

CMake Warning (dev) at /usr/local/share/cmake-3.30/Modules/FetchContent.cmake:1953 (message):
Calling FetchContent_Populate(fmt) is deprecated, call
FetchContent_MakeAvailable(fmt) instead. Policy CMP0169 can be set to OLD
to allow FetchContent_Populate(fmt) 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/fmt.cmake:27 (FetchContent_MakeAvailableWithArgs)
CMakeLists.txt:160 (include)
This warning is for project developers. Use -Wno-dev to suppress it.

There're differences between MakeAvailable and Populate, and we rely on these differences now.

So it cannot be simply replaced. Need some investigation.
