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}`
