# - Find SDL2

# Find the SDL2 headers and libraries

# SDL2::SDL2 - Imported target to use for building a library
|
||||
# SDL2::SDL2main - Imported interface target to use if you want SDL and SDLmain.
|
||||
# SDL2_FOUND - True if SDL2 was found.
|
||||
# SDL2_DYNAMIC - If we found a DLL version of SDL (meaning you might want to copy a DLL from SDL2::SDL2)
