+FindSdlAndroid
+----------------------
+
+Locate various executables that are essential to creating an Android APK archive.
+This find module uses the FindSdlAndroidBuildTools module to locate some Android utils.
+
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+This module defines the following :prop_tgt:`IMPORTED` target(s):
+
+`` SdlAndroid::aapt2 ``
+   Imported executable for the "android package tool" v2
+
+`` SdlAndroid::apksigner``
+   Imported executable for the APK signer tool
+
+`` SdlAndroid::d8 ``
+   Imported executable for the dex compiler
+
+`` SdlAndroid::zipalign ``
+   Imported executable for the zipalign util
+
+`` SdlAndroid::adb ``
+   Imported executable for the "android debug bridge" tool
+
+`` SdlAndroid::keytool ``
+   Imported executable for the keytool, a key and certificate management utility
+
+`` SdlAndroid::zip ``
+   Imported executable for the zip, for packaging and compressing files
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+`` AAPT2_BIN ``
+   Path of aapt2
+
+`` APKSIGNER_BIN ``
+   Path of apksigner
+
+`` D8_BIN ``
