Merge modifications for Lazarus - FPC compiler to the current branch

[HuguesDug]

Hello,

I found this excellent work inside github : a port of your wrapper to Lazarus/FPC compiler. https://github.com/t-edson/LazarusOpenCV

I suggest you include the modifications in your own code with compiler switches so all the community can benefit from the updates you regularly make.

Thanks

Yes, it's a good idea. But I think it's better to spend time developing a wrapper for OpenCV 4.5.1
