Arguments with default values are considered to be always present. Use the `get()` method in these cases to check their
actual value instead.
String keys like `get<String>("@image1")` return the empty string `""` by default - even with an empty default value.

2. OPENCV_SAMPLES_DATA_PATH_HINT environment variable
3. OPENCV_SAMPLES_DATA_PATH environment variable

5. Scan `<source>/{,data,samples/data}` directories if build directory is detected or the current directory is in source tree.
6. Scan `<install>/share/OpenCV` directory if install directory is detected.
