This has nothing to do with GStreamer. The problem is, that libGAL.so is missing the correct 'soname'. As a result, libgstimxg2d.so is not linked correctly. > There are no elf files involved.

No, install_lib is for proper versioned shared libraries. If you need extra links, then you can add those with install_link.
