In the case of re-doing, `configure` and `configure.bat` pass an extra
parameter to the `QtProcessConfigureArgs.cmake`. As a result, CMake
removes CMakeCache.txt and CMakeFiles/ before the reconfiguration. If
the user is using CMake 3.24 or newer, this is achieved by passing
the `--fresh` option to CMake call. In older CMake(s), CMakeCache.txt
and CMakeFiles/ found in CMAKE_BINARY_DIR will be removed using a
file(REMOVE_RECURSIVE call.
[ChangeLog] The -redo option now additionally removes existing
CMakeCache.txt file, and CMakeFiles/ directory, and recreates them from
scratch.
