+Build system tries to get ncnn's dependencies and link with them
+likely(?) expecting a static ncnn. These checks have caused issues
+before [1] and even if that was fixed, there is no reason to do
+this and DEPEND for nothing.
+
+Cannot do -DUSE_SYSTEM_NCNN=no given there is another condition
+using that that we do need.
