OpenCV Cross Compilation for NI Linux RT

I would like to use OpenCV to develop an application using the C & C++ Development Tools for NI Linux Real-Time (Eclipse), I am using Windows OS trying to cross-compile for a NI Linux RT.
But after days of trying to solve one problem, I decided to ask for help. I am following the tutorial shown on figure "Tutorial Screen" but the NI compilers x86_64-nilrt-linux-gcc.exe and x86_64-nilrt-linux-g++.exe does not seem to work to compile OpenCV for a NI Real-Time System. I also tried to use the pre-build OpenCV binaries from NI Vision OpenCV Utilities (located on C:\Program Files (x86)\National Instruments\NIVision OpenCV Utilities\opencv\include\linux\opencv2) but although the C & C++ Development Tools for NI Linux Real-Time (Eclipse) found the libraries, it could not recognize a simple "Mat" object from OpenCV (I am also sending a print screen of this project).
I would really appreciate any help.

Best Regards,
Saulo.
