g++ 'pkg-config opencv --cflags' hello_opencv.cpp -o hello_opencv 'pkg-config opencv --libs'
and I got the error as 
g++: error: pkg-config opencv --cflags: No such file or directory
g++: error: pkg-config opencv --libs: No such file or directory

you need backticks (`) around the pkg-config parts, not single quotes (').

the idea behind that is to run e.g. pkg-config opencv --cflags from the shell, and replace that with the outcome of it.

so, your cmdline should look like this:

g++ `pkg-config opencv --cflags` hello_opencv.cpp -o hello_opencv `pkg-config opencv --libs`

    ^- here         and  here -^
