Prefix-relative subdirectory for deploying program executables on some target platforms.
This variable is defined by the script named by QT_DEPLOY_SUPPORT . It should only be used as part of deployment during installation or a post-build rule.
注意： This is a low-level deployment API variable, and should only be used in advanced use-cases that are not covered by the higher-level API commands, like qt_generate_deploy_app_script .
This variable was introduced in Qt 6.7.
On Unix derivatives, projects should use
QT_DEPLOY_LIBEXEC_DIR
in their deploy scripts to avoid hard-coding a particular directory in which to deploy helper executables that are local to the project.
For example, projects using
QtWebEngine
would deploy the
QtWebEngineProcess
executable to this directory.
QT_DEPLOY_LIBEXEC_DIR
defaults to the value of
${CMAKE_INSTALL_LIBEXECDIR}
(usually
libexec
), which is provided by CMake's
GNUInstallDirs
module. To change the value of
QT_DEPLOY_LIBEXEC_DIR
, ensure that the project sets
CMAKE_INSTALL_LIBEXECDIR
先于
核心
package is found.
The
QT_DEPLOY_LIBEXEC_DIR
path is relative to
QT_DEPLOY_PREFIX
.
This variable is not meaningful when deploying into a macOS app bundle and should not be used for that scenario.
