Why cannot I compile the opencv? - opencv

Question

I'm using Centos 7.2. I tried to compile and install opencv using cmake.
I run these commands:
git clone https://github.com/opencv/opencv
cd opencv
mkdir -p build
cd build
The problem happens when I run the command:
cmake -D BUILD_opencv_gpu=OFF -D WITH_EIGEN=ON -D WITH_TBB=ON -D WITH_CUDA=OFF -D WITH_1394=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/ghome/mypath/software/try_opencv/installed ..
I have tried many solutions, such as downloading the latest version, compiling with -D BUILD_opencv_ts=0. But none of them helps.
I have been stuck in this problem for hours and I cannot solve it. The problem message is as follows:

Thank you all for helping me!!!

Since the error seems in downloading ippicv, if you don't need it strictly you can simply disable it adding -D WITH_IPP=OFF in your cmake configuration line.
A very similar question was asked here.
It could also be that updating CMake might solve the problem. To do so, if you are in a Linux environment, consider this guide.
