Fix FetchContent_Populate deprecated warning message

[ypujante]

When compiling with a recent version of CMake, the following warning is issued

CMake Warning (dev) at /Applications/CMake.app/Contents/share/cmake-3.30/Modules/FetchContent.cmake:1953 (message):
  Calling FetchContent_Populate(re-logging) is deprecated, call
  FetchContent_MakeAvailable(re-logging) instead.  Policy CMP0169 can be set
  to OLD to allow FetchContent_Populate(re-logging) to be called directly for
  now, but the ability to call it with declared details will be removed
  completely in a future version.
