Before running

I had to
sudo apt-get install libssl-dev

@zebrassimo,

Nice catch, much appreciated.

Saved me from starting over.

Looks like there needs to be a pull request.

I also need this one from vjekoslavdiklic (realsenseai/librealsense#10033 (comment))
I was able to solve this by using gcc 7 and g++ 7.

sudo apt-get install gcc-7 g++-7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60 --slave /usr/bin/g++ g++ /usr/bin/g++-7
sudo update-alternatives --set gcc "/usr/bin/gcc-7"

I don't think opengl is needed to be installed on rapsberry pi 4b. It is already there.
