I followed the OpenCV site directions at http://docs.opencv.org/3.0-beta/doc/tutorials/introduction/windows_install/windows_install.html to build this. I downloaded all the files listed without problems. When I get to the part in 6(k) saying: "Now navigate to the extracted folder and enter inside it by using this console window. You should have a folder containing files like Install, Make and so on. Use the dir command to list files inside your current directory. Once arrived at this directory enter the following command:
configure.exe -release -no-webkit -no-phonon -no-phonon-backend -no-script -no-scripttools -no-qt3support -no-multimedia -no-ltcg"
I tried, but not sure where to look in the Qt folder for the listed Install, Make files. The ones I did find keep getting error saying, the above is not recognized as an internal or external command when I run the above command. Would appreciate some help!!
