4 years ago I have the same issue and I spent a day (google ...)and almost still didn't solve it...
but ...
I realized that I have installed 3 versions of CUDA(10.0, 10.1, 10.2)...maybe this is the reason, so I use uninstall tools to uninstall all the CUDA packages...
a clean windows!
then restart PC, and reinstall the cuda10.1 with cudnn7.6,
run build.ps1
this works!

4 years ago @dayfixer Congratulations！ However, my laptop has only one version of CUDA(10.0) and my classmates also encountered the same problem. I tried build.ps1 at first but I can only use command line to detect pictures, when I run darknet.exe detector...test.mp4 I got the "GPU isnt used. Demo needs OpenCV for webcam images" in cmd, so I tried to compile it in a legacy way. Sadly I didnt make it in neither ways.

4 years ago add Environment variable OPENCV_DIR, value like D:\opencv4.4\build
and the lib path of opencv must be added in PATH, value like %OPENCV_DIR%\x64\vc15\bin,
when u run build.ps1, you can find the cmake output ,such as
Mode LastWriteTime Length Name

t change CUDA/Device/Code Generation, the value is sill "compute30,sm30;compute 75,sm75". I tried deleted the "75value" both in VS and darknet.vcxproj but it didnt work. Hope to get answer soon, thanks a lot!
