Hotfix for cmake configs which use include() for the module list (eg.
posix_sitl_ekf2.cmake or snapdragon). In that case the cmake parser did
not find any modules and thus the param list was empty.
The proper fix will be to parse the include() statements correctly.
- the only difference really is, that scope (the configuration.cmake) is already passed
to px_process_params via the argument --scope. The Paths in --scope are evaluated w.r.t
the path to src provided via the -s /--src-path argument.
- if no --scope is proveided. the Old scheme by simply walking the full --src-path directory
is applied
