Hi,

I try to follow the instruction to build this Open Model Zoo Demos in windows OS and I ran into these error messages:

Any idea?

Hi DarkHorse,

Thank you for reaching out to us.

To build the demos, you need to source OpenVINO™ environment and OpenCV. To install OpenCV for OpenVINO, see the instructions on GitHub.

Here are the steps for installing prebuilt OpenCV on Windows OS:

1. Download OpenCV windows package on the official OpenCV releases page Windows archive contains VC postfix, e.g.: opencv-4.6.0-vc14_vc15.exe
2. Extract the archive
3. Setup environment variables by running the script opencv\build\setup_vars_opencv4.cmd

Additionally, you'll need to specify the "OpenCV_DIR" path before building the demos. Run the following command in the command prompt:

set "OpenCV_DIR=<OpenCV_Installation_Dir>\opencv\build"

Regards,

Hairul
