This is actually off-topic for this forum.
It appears you imported the project correctly but the project is in error.
Or is for a different version of opencv.

/home/kishan/workspace/iControl/analytics//libeI_Analytics.so: undefined reference to `cv::putText(cv::Mat&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, cv::Point_<int>, int, double, cv::Scalar_<double>, int, int, bool)'

Means cv::putText(... couldn't be found in the libraries you provided.
Use pkg-config to get the link options for opencv.
In my installation {new lines added for readability):
$ pkg-config --libs  opencv
-lopencv_calib3d -lopencv_contrib -lopencv_core 
-lopencv_features2d -lopencv_flann -lopencv_gpu 
-lopencv_highgui -lopencv_imgproc -lopencv_legacy 
-lopencv_ml -lopencv_objdetect -lopencv_ocl 
-lopencv_photo -lopencv_stitching -lopencv_superres 
-lopencv_ts -lopencv_video -lopencv_videostab

The order is important.
Should work in Ubuntu depending on how you installed the libs.

This is not a CDT issue.
Since this forum is for addressing CDT issues,
you should address future questions to a forum dedicated to opencv
or perhaps stackoverflow.com

It can also be an attempt to link together modules compiled with different C++ compilers, one from Windows and the other from Linux. It won't work.
