Add functionality in Delphi program with opengl

I have to add two features to my program made in Delphi and opengl. I have the specification and the code will be provided. The idea is to implement the SSAO and Shadows from the LearnOpengl tutorial in an application with PBR. I can't make the two operations functional together with the PBR.
