This was originally removed in fe03d83703
There are apparently a bunch of different compatible libmirisdr
libraries which are actually being used that have nothing in common with
the old, unmaintained hack we built this support for.
OsmoSDR and MiriSDR support was disabled in v0.2.1 because the hardware
is rare and obsolete. I think it would be useful to completely remove
the associated code, since this will reduce the future maintenance
burden for gr-osmosdr.

CMake 3.13 is not present in older (~2 years old)
Linux distributions and GNU Radio requires min CMake
version 3.8.
All that is needed in order to avoid bumping CMake version
is to not use 'target_link_libraries' in subdirectories.
Here this is done by creating a list of needed
libraries and adding them for linking at the end (like
it was done in gr-osmosdr before porting to GNU Radio 3.8).
One thing that is lost here is 'PRIVATE' statement in case
of FCD libraries linking.
