Note that the OptiX Advanced Samples are built against OptiX 5.1.0 and while they still run with OptiX 6.5.0, they do not make use of the built-in triangle intersection on RTX boards.
They won’t work with OptiX 7.0.0 at all because that changed to a completely different API.
Instead please have a look into the last post of this sticky thread which contains a link to OptiX 7.0.0 based ports of some of the OptiX introduction examples:

They come with *.cmake scripts inside the 3rdparty/CMake folder to resolve these include directory and link library locations automatically when following the 3rdparty build setup descriptions inside the readme.
The three 64-bit DLLs need to be copied into the executable’s target directory.
The necessary steps are explained inside the README.md there.
