+By default, it uses static libs for Linux and macOS. To change that,
+open Lazarus IDE, select `Project`, `Project options`, `Compiler options`,
+change the `Build modes` to `Release-Linux`.

+The `Release-Linux` mode is defined in the file `generate_subtitles.lpi`.
+It defines a macro `SHERPA_ONNX_USE_SHARED_LIBS`.
