echo [+] BUILD SUCCESSFUL
echo     build\plex_patch.dll   - godmode DLL (inject into PMS)
echo     build\plex_inject.exe  - injector (finds or launches PMS)
echo.
echo Usage:
echo   1. Copy both files to any directory.
echo   2. Start Plex Media Server normally, then:
echo        build\plex_inject.exe
echo      Or launch PMS through the injector:
echo        build\plex_inject.exe --launch "C:\Program Files\Plex\Plex Media Server\Plex Media Server.exe"
echo   3. Verify with DebugView: look for [plex_patch INF] messages.
