Unlike most other CMake commands provided by Qt, \c{qt_deploy_qt_conf()} can
only be called from a deployment script. It cannot be called directly by the
project.
 
\cmakecommandsince 6.3
\note 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.

\section1 Description
 
Use this command when you need to generate a \l{Using qt.conf}{qt.conf} file
during deployment. The default value of any path supported by \c{qt.conf} can
be overridden with the corresponding \c{..._DIR} option. The command will only
write a path to the generated \c{qt.conf} file if it differs from the default
value.
The default values can be found at \l{Overriding Paths}.
 
The \c file_path argument expects an absolute path to the location where the
\c qt.conf file should be written to. The \l{QT_DEPLOY_PREFIX} and \l{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.
