# to come from external/windows/fobos-sdr and external/windows/fobos-regular
# in the SDRangel Windows dependency repo.

# On Linux the plugin is intended to runtime-load libfobos_sdr.so / libfobos.so.
# CMake still verifies headers and libraries early so developer builds fail with
# a clear diagnostic instead of a hidden runtime loader error.
