How to set path for cmake

Question

I am trying to build an openvino project security_barrier_camera_demo which is available in github https://github.com/openvinotoolkit/open_model_zoo/tree.

After cloning the openvinotoolkit repository in my Centos machine. I followed the commands available in the documentation to setup openvino https://github.com/openvinotoolkit/openvino/blob/master/docs/dev/build_linux.md

But while performing the build by running build_demos.sh file. I am getting this error CMake Error: Could not find CMAKE_ROOT !!! CMake has most likely not been installed correctly. Modules directory not found in /usr/share/cmake3 CMake Error: Error executing cmake::LoadCache(). Aborting.

Can someone please assist.

I also tried to install cmake from open source i.e. tar -zxvf cmake-X.Y.Z-Linux-x86_64.tar.gz and set the path to CMAKE_ROOT but still got same issue.

Tried removing and reinstalling cmake from scratch.

I am using python version 3.10 and cmake version 3.30. centos version: 7 GCC version: 4.8.5
