Subject: [PATCH] Fixed bug 5481 - iOS-specific main sources not used for CMake
 build.

Aaron Barany

The CMake build for SDL doesn't set SDLMAIN_SOURCES on iOS to the sources in src/main/ios. As a result, SDL fails to initialize since it falls back to the dummy main. Adding the line file(GLOB SDLMAIN_SOURCES ${SDL2_SOURCE_DIR}/src/main/uikit/*.c) fixes the issue.
