+FindSdlAndroidPlatform
+----------------------
+
+Locate the Android SDK platform.
+
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :prop_tgt:`IMPORTED` target(s):
+
+<none>
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This find module will set the following variables in your project:
+
+`` SdlAndroidPlatform_FOUND
+   if false, no Android platform has been found
+
+`` SDL_ANDROID_PLATFORM_ROOT
+   path of the Android SDK platform root directory if found
+
+`` SDL_ANDROID_PLATFORM_ANDROID_JAR
+   path of the Android SDK platform jar file if found
+
+`` SDL_ANDROID_PLATFORM_VERSION
+   the human-readable string containing the android platform version if found
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+These variables may optionally be set to help this module find the correct files:
+
+``SDL_ANDROID_PLATFORM_ROOT``
+  path of the Android SDK platform root directory
+
+
+Variables for locating Android platform
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+This module responds to the flags:
+
+``SDL_ANDROID_HOME
+    First, this module will look for platforms in this CMake variable.
+
+``ANDROID_HOME
+    If no platform was found in `SDL_ANDROID_HOME`, then try `ANDROID_HOME`.
+
+``$ENV{ANDROID_HOME}
+    If no platform was found in neither `SDL_ANDROID_HOME` or `ANDROID_HOME`, then try `ANDROID_HOME}`
