Hi Vasil,
Thanks for your answer.
What helped was passing -DCMAKE_FIND_ROOT_PATH=/usr option, while configuring the OOT module.
It seems like I cannot use pybombs recipes to install the OOTs.
Best regards,

Usually such errors indicate that the development files for a library are not installed (Boost in your case)

> -- Found Boost: /lib/x86_64-linux-gnu/cmake/Boost-1.71.0/BoostConfig.cmake (found suitable version "1.71.0", minimum required is "1.65") found components: system chrono thread

But it seems that you do have them. Also as you are using pybombs it should install the boost development packages in case they are not installed.

First check what is the value of the various boost variables in CMakeCache.txt

  grep -i boost /home/ubuntu/prefixes/gnuradio39/src/gr-fosphor/build/CMakeCache.txt

Then make sure that you have libboost-all-dev package installed and installed it if missing. Then delete the build directory (or CMakeCache.txt) and try a clean rebuild.
