Hey everyone, I have a problem. I am following the OOT(OutofTree) module tutorial,  
Link: [OutOfTreeModules - GNU Radio](https://wiki.gnuradio.org/index.php/OutOfTreeModules)  
and I am at the part it involves using the cmake command line. I have followed everything it said and for the parts where I am using pybombs I made the changes. I am using Gnuradio 3.8.4.0 and Ubuntu 20. I am stuck at this point and I have search for the past couple of days and my advisor to ask online. If anyone can give me hint that would be great. I have left the error behind so you can see it. This is the first time doing this so if I left something out let me know so I can add or change it. Thank you for your time.

make[2]: \*\*\* No rule to make target ‘/usr/lib/x86\_64-linux-gnu/liborc-0.4.so’, needed by ‘lib/libgnuradio-howto.so.1.0.0.0’. Stop.  
make[1]: \*\*\* [CMakeFiles/Makefile2:272: lib/CMakeFiles/gnuradio-howto.dir/all] Error 2

I was wondering if you ever figure out how to fix this error
