 # FindGradle
 # ----------
 #
 # Provides the ability to build Android AAR libraries using Gradle.
 #
 # This relies on the Qt provided Gradle, so a Qt for Android installation
 # is required.
 #
 #   gradle_add_aar(<target>
 #                  BUIDLFILE build.gradle
 #                  NAME <aar-name>)
 #
 # This builds an Android AAR library using the given ``build.gradle`` file.
 #
 #   gradle_install_aar(<target>
 #                      DESTINATION <dest>)
 #
 # Installs a Android AAR library that has been created with ``gradle_add_aar``.
