+================================================================================
+
+CMake 3.14+ natively includes support for iOS and tvOS.  SDL binaries may be built
+using Xcode or Make, possibly among other build-systems.

+When using a recent version of CMake (3.14+), it should be possible to:

+- build SDL test apps (as iOS/tvOS .app bundles)
+- generate a working SDL_config.h for iOS (using SDL_config.h.cmake as a basis)
+
+To use, set the following CMake variables when running CMake's configuration stage:
+
+- `CMAKE_SYSTEM_NAME=<OS>`   (either `iOS` or `tvOS`)
+- `CMAKE_OSX_SYSROOT=<SDK>`  (examples: `iphoneos`, `iphonesimulator`, `iphoneos12.4`, `/full/path/to/iPhoneOS.sdk`,
