message: Add LD_PRELOAD instruction to be able to run Java code that calls OpenCV functions that use the Intel MKL library.

  That is it, whenever you start a new project just add the OpenCV user library that you have defined
  to your project and you are good to go. Enjoy your powerful, less painful development environment :)

  +Running Java code with OpenCV and MKL dependency
  +------------------------------------------------
  +
  +You may get the following error (e.g. on Ubuntu) if you have built OpenCV with MKL library with some Java code that calls OpenCV functions
  +that use Intel MKL:
  +> Intel MKL FATAL ERROR: Cannot load libmkl_avx2.so or libmkl_def.so.
  +
  +One solution to solve this on Linux consists in preloading the Intel MKL library (either run the command in a terminal or add it to your `.bashrc` file).
  +Your command line should be something similar to this (add `$LD_PRELOAD:` before if you have already set the `LD_PRELOAD` variable):
  +> export LD_PRELOAD=/opt/intel/mkl/lib/intel64/libmkl_core.so:/opt/intel/mkl/lib/intel64/libmkl_sequential.so
  +
  +Then, run the Eclipse IDE from a terminal that have this environment variable set (`echo $LD_PRELOAD`) and the error should disappear.
