In my opinion it is better to switch gnuradio to maint-3.8 branch and reinstall
or you'll need to edit gr-osmosdr's CMakeList.txt
In CMakeList.txt on line 115 (my maint-3.8 branch)
find_package(Gnuradio "3.8" REQUIRED COMPONENTS blocks uhd) # Side effect
of MODULE_PATH getting prepended with system components
To use it with gnuradio's master branch you will need to change "3.8" to "3.9"
and if you don't use/have uhd just removed it.
BTW for new projects SoapySDR and SoapyRTLSDR are probably a better
alternatives to gr-osmosdr.

Neither my fork nor igorauad's contains such check in CMakeLists.txt:179
https://github.com/velichkov/gr-osmosdr/blob/a76d332/CMakeLists.txt#L179
https://github.com/igorauad/gr-osmosdr/blob/f3905d3/CMakeLists.txt#L179
Most probably you are still using the master branch. The HEAD of my branch is
a76d332, make sure that you are using this commit.

That is to be expected.

In this case cross compiling everything on your desktop might be a better
alternative.
BTW why did you choose to install gnuradio from source? I just checked and
there are gnuradio and gr-osmosdr for arm64 architecture in the debian
repositories.
