I face a problem when installing OpenCV 4.0 after building OpenCV, which is stated as follows:
Install the project...
-- Install configuration: "Release" CMake Error at cmake_install.cmake:41 (file): file INSTALL cannot find "/home/user/OpenCV/opencv/build/3rdparty/ippicv/ippicv_lnx/icv/readme.htm".
Makefile:73: recipe for target 'install' failed make: * [install] Error 1
The OpenCV cannot be installed, which shows that I missed the ippicv files. I downloaded the ippicv file from the official website (https://github.com/opencv/opencv_3rdparty/blob/ippicv/master_20170822/ippicv/ippicv_2017u3_lnx_intel64_general_20170822.tgz),
and extract the file to /home/user/OpenCV/opencv_contrib/modules. Besides, I changed the path in /home/user/OpenCV/opencv/3rdparty/ippicv/ippicv.cmake from "https://raw.githubusercontent.com/opencv/opencv_3rdparty/${__commit_hash}/" to "/home/user/OpenCV/opencv_contrib/modules/ippicv/"
However, I still face the problem which shows that the file is likely to be missed. Please help.
