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}`
|
