I cloned the package from the source and experimented perfectly, later i uninstalled the ROS and openCV and reinstalled. Now i compiled the package using catkin_make successfully but when i try to run the node i am getting following error.

[ WARN] (2015-08-06 23:22:31.328) Settings.cpp:960::createDescriptorExtractor() Find-Object is not     built with OpenCV xfeatures2d module so Brief cannot be used!
  [FATAL] (2015-08-06 23:22:31.328) FindObject.cpp:56::FindObject() Condition (detector_ != 0 && extractor_ != 0) not met!

   *******
FATAL message occurred! Application will now exit.

Please clarify how to fix this issue
