For SDL, (typed in mail from memory so it is untested, and ignoring
some of the SDL/OS X quirks about SDLMain.m for clarity),

PROJECT(MySDLProject)
FIND_PACKAGE(SDL)
INCLUDE_DIRECTORIES(${SDL_INCLUDE_DIR})
ADD_EXECUTABLE(MySDLProg MACOSX_BUNDLE main.c)
TARGET_LINK_LIBRARIES(MySDLProject ${SDL_LIBRARY})
