SDL headers should now be included as `#include <SDL3/SDL.h>`. Typically that's the only header you'll need in your application unless you are using OpenGL or Vulkan functionality.
CMake users should use this snippet to include SDL support in their project:
```
find_package(SDL3 REQUIRED CONFIG REQUIRED COMPONENTS SDL3)
find_package(SDL3 REQUIRED CONFIG COMPONENTS SDL3main)
if(TARGET SDL3::SDL3main)
target_link_libraries(mygame PRIVATE SDL3::SDL3main)
endif()
target_link_libraries(mygame PRIVATE SDL3::SDL3)

Autotools users should use this snippet to include SDL support in their project:
```
PKG_CHECK_MODULES([SDL3], [sdl3])
```
and then add $SDL3_CFLAGS to their project CFLAGS and $SDL3_LIBS to their project LDFLAGS
Makefile users can use this snippet to include SDL support in their project:
```
CFLAGS += $(shell pkg-config sdl3 --cflags)
LDFLAGS += $(shell pkg-config sdl3 --libs)
```
