I am trying to build OpenCV from Source using CMake.
I have used master branch to install.
I installed Eigen via apt-get sudo apt-get install libeigen3-dev.
And cmake shows eigen 3.3.4 is installed.
But when I did 'make', it showed the following error that Eigen/Core is not detected.
/opencv/modules/core/include/opencv2/core/private.hpp:66:12: fatal error: Eigen/Core: No such file or directory
#include < Eigen/Core >
compilation terminated.
How can I add Eigen to C++ library list?
