Download opencv 3.2

You have to :

1. Download opencv 3.2 3.2
2. git clone https://github.com/opencv/opencv_contrib.git
3. run cmake give opencv path
4. if you use VS2015 disable cuda (in build and with cmake variables)
5. give path to opencv_contrib/modules (where you clone it and don't forget modules)
6. generate
7. open project if you have vs and build solution (drink a coffee)

You have to :

1. Download opencv 3.2 unzip it (in C:\Users\Laurent.PC-LAURENT-VISI\Downloads\ on my computer)
2. git clone https://github.com/opencv/opencv_contrib.githttps://github.com/opencv/opencv_contrib.git ( in g:/lib on my computer)
3. run cmake GUI. give opencv pathpath in where is source file (C:\Users\Laurent.PC-LAURENT-VISI\Downloads\opencv/sources
4. press configure
5. if you use VS2015 disable cuda (in build (12 check box)and with_cuda and with cmake variables)withcufft )
6. give path to opencv_contrib/modules (where you clone it and don't forget modules)modules g:/lib/opencv_contrib/modules)
7. generate
8. open project if you have vs and build solution (drink a coffee)

Now build face sample in opencv_contrib

1. run cmakecmake
2. where is the source code = G:/Lib/opencv_contrib/modules/face/samples
3. where to build binaries = C:/Users/Laurent.PC-LAURENT-VISI/Downloads/opencv/sources/samples
4. fill all field like this
5. cmake cannot find opencv : give path C:\Users\Laurent.PC-LAURENT-VISI\Downloads\opencv\sources in cmake variables OpenCV_DIR

build project and no errors...
