Subject: [PATCH] Fix qt5_make_output_file macro for paths containing dots

Commit 89bd5a7e broke CMake projects that use dots in their build
paths, because the used regular expression matches the directory part
of the path as well.

The regex wants to achieve the same as get_filename_component(...
NAME_WLE) which is available since CMake 3.14. Re-implement the
NAME_WLE functionality for older CMake versions by using multiple
get_filename_component calls.

Fixes: QTBUG-81715
Task-number: QTBUG-80295
