# RetroShare macOS Portability & Deployment Packaging Script
# Designed for macOS environment with CMake
# ------------------------------------------------------------------------------
# Why this is more than a one-liner: macdeployqt IS the standard tool and does the
# heavy lifting (bundling Qt frameworks, fixing rpaths). The extra steps around it
# handle RetroShare specifics that macdeployqt does not cover:
#   - RetroShare refuses to load plugins on macOS unless they end in ".dylib",
#     so built plugins are copied/renamed accordingly.
#   - macdeployqt skips .so plugins, so each plugin is passed via -executable=.
#   - Qt imageformats (SVG) are force-copied (macdeployqt sometimes misses them).
#   - Ad-hoc codesign is mandatory on Apple Silicon, otherwise the app won't run.
