# 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.

# Windows: official builds expect the import libraries / DLLs to come from

# external/windows/fobos-sdr and external/windows/fobos-regular in the SDRangel
|

# Windows dependency repo (handled in the WIN32 block below).

# Linux: the plugin does NOT link against or #include the Fobos SDK. fobosworker.{h,cpp}
|

# forward-declare fobos_dev_t and define their own function-pointer typedefs, then load
|
||||
# libfobos_sdr.so / libfobos.so at runtime through QLibrary. Consequently neither the
|
||||
# development headers nor the runtime libraries are required at build time, and any
|
||||
# combination of backends (Agile, Regular, both or none) is resolved at runtime.
|
||||
# The detection below is therefore best-effort and ADVISORY ONLY: it never fails the
|
||||
# build, and it is multilib-aware (lib/lib64) so it does not depend on a possibly
|
||||
# incorrect libfobos_sdr.pc libdir.
