Upon further troubleshooting:

Compile error appears to be related to a missing header file; cv.h. This is probably related to the OpenCV dependency. OpenCV and the development files where installed with the command line; sudo dnf install opencv-devel. It completed successfully. A search of the file system could not locate this header file. To correct that, I downloaded the latest OpenCV and built and installed the package. The cv.h file still cannot be located. Perhaps a previous version of OpenCV is needed. Can anyone confirm that?

Thanks.
