\c{QT_DEPLOY_PREFIX} provides the base deployment directory. The other
\c{QT_DEPLOY_..._DIR} variables should be treated as relative to this location.
The value of \c{QT_DEPLOY_PREFIX} may be relative or absolute, so projects
should not assume one or the other in any given situation. A relative path is
expected to be treated as relative to the current working directory, as seen
by the build tool (ninja, make, and so on) at install time.

The default value is \c{$ENV{DESTDIR}${CMAKE_INSTALL_PREFIX}}, which is the
base location CMake uses during installation. If that evaluates to an empty
string, the default value will be a dot (.) instead, which is generally the
appropriate value when deploying as part of a post-build rule. This two-step
fallback logic ensures that projects can assume \c{QT_DEPLOY_PREFIX} will not
be an empty string, so it can safely be used as part of a path like
\c{${QT_DEPLOY_PREFIX}/${QT_DEPLOY_BIN_DIR}}.

To change the value of \c QT_DEPLOY_PREFIX, the project can be configured
with a custom \l CMAKE_INSTALL_PREFIX as described in
\l {Command Line cmake invocation}.

The \l DESTDIR environment variable can also be used to modify the final
installation, and thus deployment, location.

Projects should rarely need to use this variable. In typical scenarios, deploy
scripts should assume that the working directory is already set to the base
install location and just use the prefix-relative \c{QT_DEPLOY_..._DIR}
variables.

\summary {Prefix-relative subdirectory for deploying runtime binaries on some target platforms.}

\include cmake-deploy-var-usage.qdocinc

\cmakevariablesince 6.3
\preliminarycmakevariable

Projects should use \c QT_DEPLOY_BIN_DIR in their deploy scripts to avoid
hard-coding a particular directory in which to deploy the following types of
binaries:

\list
\li Executables on all platforms.
\li DLLs on Windows.
\endlist

\c QT_DEPLOY_BIN_DIR defaults to the value of \c${CMAKE_INSTALL_BINDIR}
(usually \c{bin}), which is provided by CMake's \l{GNUInstallDirs} module.
To change the value of \c QT_DEPLOY_BIN_DIR, ensure that the project sets
\c{CMAKE_INSTALL_BINDIR} before the \c Core package is found.

The \c QT_DEPLOY_BIN_DIR path is relative to \l{QT_DEPLOY_PREFIX}.

This variable is not meaningful when deploying into a macOS app bundle and
should not be used for that scenario.

\endlist

\c QT_DEPLOY_LIB_DIR defaults to the value of \c${CMAKE_INSTALL_LIBDIR}
(usually \c{lib} or \c{lib64}), which is provided by
CMake's \l{GNUInstallDirs} module.
To change the value of \c QT_DEPLOY_LIB_DIR, ensure that the project sets

Projects should use \c QT_DEPLOY_PLUGINS_DIR in their deploy scripts to avoid

\c QT_DEPLOY_PLUGINS_DIR defaults to the value \c{plugins}. To change the value
of \c QT_DEPLOY_PLUGINS_DIR, set it in the project deployment script
before \c QT_DEPLOY_SUPPORT is included.

The \c QT_DEPLOY_PLUGINS_DIR path is relative to \l{QT_DEPLOY_PREFIX}.

This variable is not meaningful when deploying into a macOS app bundle and
should not be used for that scenario. Apple's macOS app bundle guidelines
require all plugins to be deployed to the \c{PlugIns} subdirectory of the
bundle contents.

Projects should use \c QT_DEPLOY_QML_DIR in their deploy scripts to avoid

\c QT_DEPLOY_QML_DIR defaults to the value \c{qml}. To change the value

The \c QT_DEPLOY_QML_DIR path is relative to \l{QT_DEPLOY_PREFIX}.

This variable is not meaningful when deploying into a macOS app bundle and
should not be used for that scenario. Apple's macOS app bundle guidelines
require all plugins to be deployed to the \c{PlugIns} subdirectory of the
bundle contents, and all other non-binary files should generally be under the
\c{Resources} subdirectory. The different parts of a QML module therefore need
to be deployed to different locations within the app bundle.
