OpenCV building notes

So I gave the following 2 commands.

make

sudo make install

There were 2 errors in the first command saying "permission denied".  I ignored it because I didn't know how to fix it!

Then I executed the second command.  It seemed to start OK,and so I have to wait for 4+ hours!

Now we are ready to start the build! To compile, run make, then install with make install:

make

sudo make install

As you can see from the image, this will take a LONG time ... over four and a half hours to compile!
