moonray_gui_v2 uses the dynamic linker API (dlopen/dlclose/dlerror) from libdl. The ASWF CI images for 2023–2025 all use GCC 11.2 (per VFX Reference Platform), but the linker flag --as-needed (the default on modern Linux distributions) causes libdl to be dropped when it is not listed as a direct dependency. Previously libdl was pulled in transitively by another linked library; with the libraries present in these images it is not, so it must be listed explicitly.
