Yes. Static libraries (.a files) don't contain the dependency information found in shared object (.so).
So when linking STATIC_BUILD=NO, only the direct dependencies need to be listed (it doesn't hurt to list all).
With STATIC_BUILD=YES, all dependencies must be listed, and in a specific order (direct first).
