Re: Problems with gr-modtool on Ubuntu 20.04 (gnuradio 3.10.4)

Hi Michael,

Your problem looks a lot like one described in the USRP manual https://files.ettus.com/manual/page_build_guide.html#generate_unix

> If you encounter this issue, ensure that /usr/bin appears before /bin in the PATH environment variable of the process executing CMake. Alternatively, you can pass the CMAKE_FIND_ROOT_PATH configuration variable to CMake with a value of /usr to point it to the right starting directory for filesystem item searches.
