qt_deploy_qt_conf▲
Write a qt.conf file at deployment time.
The command is defined in the Core component of the Qt6 package, which can be loaded like so:
find_package(Qt6 REQUIRED COMPONENTS Core)Unlike most other CMake commands provided by Qt, qt_deploy_qt_conf() can only be called from a deployment script. It cannot be called directly by the project.
This command was introduced in Qt 6.3.
This command is in technology preview and may change in future releases.
This command does not usually need to be called directly. It is used internally by other higher level commands, but projects wishing to implement more customized deployment logic may find it useful.

)Description▲
Use this command when you need to generate a qt.conf file during deployment. The default value of any path supported by qt.conf can be overridden with the corresponding ..._DIR option. The command will only write a path to the generated qt.conf file if it differs from the default value. The default values can be found at Overriding Paths.
The file_path argument expects an absolute path to the location where the qt.conf file should be written to. The QT_DEPLOY_PREFIX and QT_DEPLOY_BIN_DIR variables can be used to dynamically specify a path relative to the deployment binary directory, as shown in the example below. This helps avoid hard-coding an absolute path.
Example▲
# The following script must only be executed at install time
set(deploy_script "${CMAKE_CURRENT_BINARY_DIR}/deploy_custom.cmake")
file(GENERATE OUTPUT ${deploy_script} CONTENT "
include(\"${QT_DEPLOY_SUPPORT}\")
qt_deploy_qt_conf(\"\${QT_DEPLOY_PREFIX}/\${QT_DEPLOY_BIN_DIR}/qt.conf\"
DATA_DIR \"./custom_data_dir\"
TRANSLATIONS_DIR \"./custom_translations_dir\"
)
")
install(SCRIPT ${deploy_script})
