0033319: Coding - Static linking fails with unresolved symbols due to linking order and missing transitive dependencies

The absence of target_link_libraries calls for static libraries caused CMake to fail
in modeling the link dependencies correctly.
This fix ensures that CMake correctly exports the dependencies in OpenCASCADEConfig.cmake and
resolves downstream linking errors for projects that link against static OpenCASCADE libraries.
