\title QT_ANDROID_MULTI_ABI_FORWARD_VARS
\target cmake-variable-QT_ANDROID_MULTI_ABI_FORWARD_VARS

\summary {Allows to share CMake variables in multi-ABI builds}

\cmakevariablesince 6.4.2
\preliminarycmakevariable
\cmakevariableandroidonly

The \c{QT_ANDROID_MULTI_ABI_FORWARD_VARS} variable allows specifying the list of
CMake variables that need to be forwarded from the main ABI project to
ABI-specific subprojects. Due to the specifics of the Multi-ABI project build
process, there is no generic way to forward the CMake cache variables
that are specified either in the command line or in another similar way.

A typical use case for the variable is propagating CMake cache variables
specified in the command line. For example, a project has two variables
\c{PROJECT_WIDE_VARIABLE1} and \c{PROJECT_WIDE_VARIABLE2} that affect the
project configuration:
\badcode
cmake_minimum_required(VERSION 3.18)

project(MyProject LANGUAGES CXX)

find_package(Qt6 REQUIRED COMPONENTS Core)

qt_add_executable(MyApp main.cpp)

if(PROJECT_WIDE_VARIABLE1)
    target_sources(MyApp PRIVATE sourcefile1.cpp)
endif()
if(PROJECT_WIDE_VARIABLE2)
    target_sources(MyApp PRIVATE sourcefile2.cpp)
endif()
\endcode

The above contents of \c{CMakeLists.txt} enable you to control how
\c{MyApp} is built by setting the corresponding CMake variables from the
command line:
\badcode
qt-cmake -S<source directory> -B<build directory> \
    -DPROJECT_WIDE_VARIABLE1=ON \
    -DPROJECT_WIDE_VARIABLE2=ON \
    -DQT_ANDROID_MULTI_ABI_FORWARD_VARS="PROJECT_WIDE_VARIABLE1;PROJECT_WIDE_VARIABLE2"
\endcode

When configuring the application for desktop, \c{PROJECT_WIDE_VARIABLE1} and
\c{PROJECT_WIDE_VARIABLE2} are visible in CMake listings and scripts as global
cache variables. This doesn't work for Android Multi-ABI builds because
ABI-specific subprojects do not inherit the cache variables from the main-ABI
project. This issue can be solved by passing the list of required variables to
the \c{QT_ANDROID_MULTI_ABI_FORWARD_VARS} variable, so both
\c{PROJECT_WIDE_VARIABLE1} and \c{PROJECT_WIDE_VARIABLE2} values will be
propagated to the ABI-specific builds.

The variable can be also defined in the project's CMakeLists.txt:
\badcode
...
qt_add_executable(MyApp main.cpp)
...
if(ANDROID)
    set(QT_ANDROID_MULTI_ABI_FORWARD_VARS "PROJECT_WIDE_VARIABLE1;PROJECT_WIDE_VARIABLE2")
endif()
...
\endcode

Setting the variable in this way allows you to have a predefined set of
variables that will always be forwarded to abi-specific projects.

\note The forwarding is done in the target finalizer, which is implicitly
called when \l{qt6_add_executable}{qt_add_executable()} is used. The
finalization occurs automatically when using CMake 3.19 or later.

The option automatically detects available ABIs of Qt for Android and uses them to

supplied by the Qt installer, with the corresponding naming of the directories.

    android_arm64_v8a

    android_x86_64

The variable is set to FALSE by default.
