what does this warning mean? warning : field of class type without a DLL interface used in a class with a DLL interface

visual studio 2019 cmake latest version opencv zip from master branch today (7/10/20) python 3.7 cuda 10.2/cudnn windows 64bit win10

I built with no errors in cmake, then I opened the project in VS and started building the ALL_BUILD file. I am getting a bunch of these warnings regarding the DLL. my PC fan is also extremely loud. should I be concerned? should I try installing with anaconda instead?
