Description

When building for Android Examples with 

set_target_properties(examplename PROPERTIES
    #Prevent name clash with build subdirectory on case-insensitive file systems
    OUTPUT_NAME examplename
)

we get the warning

C:\Qt\6.6.0\android_x86_64\lib\cmake\Qt6Core\Qt6CoreMacros.cmake:2754: warning: Qt policy QTP0002 is not set: Target properties that specify android-specific paths may contain generator expressions but they must evaluate to valid JSON strings.  Check https://doc.qt.io/qt-6/qt-cmake-policy-qtp0002.html for policy details. Use the qt_policy command to set the policy and suppress this warning. C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6AndroidMacros.cmake:926 (__qt_internal_setup_policy) C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6AndroidMacros.cmake:65 (_qt_internal_android_format_deployment_paths) C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6AndroidMacros.cmake:1352 (qt6_android_generate_deployment_settings) C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:651 (_qt_internal_android_executable_finalizer) C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:651 (cmake_language) C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:745 (_qt_internal_finalize_executable) C:/Qt/6.6.0/android_x86_64/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:715:EVAL:1 (qt6_finalize_target) CMakeLists.txt:DEFERRED

Then the error "Target is not an application so not building an APK"

and then "Cannot read from deployment settings json"

Investigation:

So, setting the policy fixes this:

qt_policy(SET QTP0002 NEW)
