Description
Adding UiTools as project dependency messes up project and android target tries to link host OS (macOS) qt libraries instead of android native ones. Depending on position of UiTools in CMake find_package project either fails to configure or switches some libs to native mac one instead of android ones.
This fails to configure completely android project
find_package(Qt6 COMPONENTS REQUIRED UiTools Core Widgets Network PrintSupport Svg Quick Qml QuickWidgets)
and this configures project but wrong libs get linked into project
find_package(Qt6 COMPONENTS REQUIRED Core Widgets UiTools Network PrintSupport Svg Quick Qml QuickWidgets)
here is minimal repro CMakeLists.txt
cmake_minimum_required(VERSION 3.20.0)
project(android)
find_package(Qt6 COMPONENTS REQUIRED Core Widgets UiTools Network PrintSupport Svg Quick Qml QuickWidgets)
# just dummy lib
file(WRITE ${CMAKE_CURRENT_BINARY_DIR}/main.cpp "int main() { return 0; }")
add_library(simple SHARED ${CMAKE_CURRENT_BINARY_DIR}/main.cpp)
target_link_libraries(simple PRIVATE Qt6::Core Qt6::Widgets Qt6::Network Qt6::PrintSupport Qt6::Svg Qt6::Quick Qt6::Qml Qt6::QuickWidgets Qt6::UiTools)
and I build this like:
mkdir build && cd build cmake -GNinja -DCMAKE_TOOLCHAIN_FILE=$QT_ANDROID_ROOT/lib/cmake/Qt6/qt.toolchain.cmake -DANDROID_SDK_ROOT="${ANDROID_SDK}" -DANDROID_NDK_ROOT="${ANDROID_NDK}" ..
built error output:

so far as workaround I found modifying
Qt/6.2.2/android_arm64_v8a/lib/cmake/Qt6/Qt6Config.cmake
adding
AND NOT "${module}" MATCHES "^UiTools$"
around line 160 after followinf line
AND NOT "${module}" MATCHES "^Tools$"
