Help building openCV + contrib libraries using CMake visual studio 2019

Hello, I am trying to build openCV with the contrib libraries but I am having trouble. I have both python 2 and 3 installed via anaconda (I am not sure if I should delete one?). I have the libraries for python 2 and 3 in the path (system environment variables).

When I try and building visual studio I am getting thousands of errors. I am running windows 10 and visual studio 2019.

Can anybody help me with some next steps to try, sorry I've been bashing my head on this for a while.

Many thanks, Richard
