I am trying to build CI2CV on windows using cmake for the first time. I get below errors while building

"CMake Error at CMakeLists.txt:17 (find\_package):Could not find a package configuration file provided by "OpenCV" with any of the following names:

```
OpenCVConfig.cmake
opencv-config.cmake

```

Add the installation prefix of "OpenCV" to CMAKE\_PREFIX\_PATH or set "OpenCV\_DIR" to a directory containing one of the above files. If "OpenCV" provides a separate development package or SDK, be sure it has been installed."

Tried to set CMAKE\_PREFIX\_PATH to location where OpenCVConfig.cmake file resides also tried the same with OpenCV\_DIR. But no luck. 

Please let me know way out of this.
