Fix to possible errors

1. If there is Segmentation Fault Error which occurs due to inappropriate power management,

$ sudo install make
$ sudo ldconfig

2. To handle ImportError: /usr/lib/aarch64-linux-gnu/libgomp.so.1: cannot allocate memory in static TLS block;

$ export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libgomp.so.1

3. OpenCV Error

CMake Error at CMakeLists.txt:66 (find_package): 
Could not find a configuration file for package "OpenCV" that is compatible
with requested version "3.0.0". `<br />
The following configuration files were considered but not accepted:  
/usr/local/lib/cmake/opencv4/OpenCVConfig.cmake, version: 4.0.0  
-- Configuring incomplete, errors occurred! 
See also "/home/nano/jetson-inference/build/CMakeFiles/CMakeOutput.log"  
See also "/home/nano/jetson-inference/build/CMakeFiles/CMakeError.log"

• This is a build problem and hence needs manual change in CMakeLists.txt

$ cd jetson-inference
$ sudo nano tools/trt-console/CMakeLists.txt

And Search for OpenCV version and change from 3.0.0 to 4.0.0
