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``.
Since 5.76.0.
