This is a fine place to ask for such help, don't worry. However, if 
you don't post some example code and the command you used to compile 
it we can't really help you. From the errors I'd guess OpenCV isn't 
being included appropriately.

Sure, using OpenCV to detect the plate, ideally deskew it if 
necessary, then sending it to Tesseract, sounds reasonable.
It sounds like that's what the example code you found does too, 
probably.
