# CategoryDlopenNotes

This header allows you to annotate your code so external tools know about
dynamic shared library dependencies.

If you determine that your toolchain doesn't support dlopen notes, you can
disable this feature by defining
[`SDL_DISABLE_DLOPEN_NOTES`](SDL_DISABLE_DLOPEN_NOTES). You can use this
CMake snippet to check for support:

```cmake
include(CheckCSourceCompiles)
find_package(SDL3 REQUIRED CONFIG COMPONENTS Headers)
list(APPEND CMAKE_REQUIRED_LIBRARIES SDL3::Headers)
check_c_source_compiles([==[
  #include <SDL3/SDL_dlopennote.h>
  SDL_ELF_NOTE_DLOPEN("sdl-video",
    "Support for video through SDL",
    SDL_ELF_NOTE_DLOPEN_PRIORITY_SUGGESTED,
    "libSDL-1.2.so.0", "libSDL-2.0.so.0", "libSDL3.so.0"
  )
  int main(int argc, char *argv[]) {
    return argc + argv[0][1];
  }
]==] COMPILER_SUPPORTS_SDL_ELF_NOTE_DLOPEN)
if(NOT COMPILER_SUPPORTS_SDL_ELF_NOTE_DLOPEN)
  add_compile_definitions(-DSDL_DISABLE_DLOPEN_NOTE)
endif()
```
