# How to run the test:
# 1. Create the build directory, e.g. /home/user/build_test_copy_file_if_different
# 2. cd /home/user/build_test_copy_file_if_different
# 3. /path/to/Qt/bin/qt-cmake /path/to/Qt/Sources/qtbase/tests/manual/cmake/test_copy_file_if_different_command
# 4. cmake --build . --parallel
# 5. ctest
