When building Qt you can use CMake variables to control the build result.
| 變量 | 描述 |
|---|---|
| QT_HOST_PATH | Location of the host Qt installation from which host tools may be used during another Qt build, either a regular one or a cross-compiling one. |
QT_FORCE_BUILD_TOOLS
|
Forces building tools even if host tools have already been found. Useful when cross-compiling Qt to ensure the SDK has cross-built tools. |
QT_FORCE_FIND_TOOLS
|
Uses Qt tools from the pre-built Qt in
QT_HOST_PATH
when you do not cross-compile. The variable only takes effect if
QT_FORCE_BUILD_TOOLS
被設為
ON
. Otherwise
QT_FORCE_FIND_TOOLS
does not affect the default behavior.

Qt 模塊的加載采用
find_package
設置各種變量。
注意： 您很少需要直接訪問這些變量。像鏈接到模塊的常見任務，應透過每個模塊定義的庫目標來完成。
例如，
find_package(Qt6 COMPONENTS Widgets)
，當成功時，使以下變量變得可用:
| 變量 | 描述 |
|---|---|
Qt6Widgets_COMPILE_DEFINITIONS
|
要使用的編譯定義列錶，當針對庫構建時。 |
Qt6Widgets_DEFINITIONS
|
要使用的定義列錶，當針對庫構建時。 |
Qt6Widgets_EXECUTABLE_COMPILE_FLAGS
|
要使用的標誌字符串，當針對庫構建可執行文件時。 |
Qt6Widgets_FOUND
|
描述是否成功找到模塊的布爾。 |
Qt6Widgets_INCLUDE_DIRS
|
要使用的 include (包括) 目錄列錶，當針對庫構建時。 |
Qt6Widgets_LIBRARIES
|
模塊導入目標的名稱：
Qt6::Widgets
|
Qt6Widgets_PRIVATE_INCLUDE_DIRS
|
要使用的私有 include (包括) 目錄列錶，當針對庫構建並使用私有 Qt API 時。 |
Qt6Widgets_VERSION
|
包含模塊版本的字符串。 |
對於找到的所有包采用
find_package
，這些變量的等價物是可用的；它們區分大小寫。
此外，還有一些變量與特定包無關，但與 Qt 安裝本身相關。
| 變量 | 描述 |
|---|---|
|
|
控製 Qt 版本的整數，
qt_
命令被轉發給 Qt 5 和 Qt 6 混閤工程。需要將其設為
5
or
6
先前分彆
find_package()
調用。
若設為
若未設置，首
|
QT_LIBINFIX
|
保持庫名稱所用中綴的字符串，當有配置 Qt 采用
-libinfix
.
|
|
|
隱藏命令開頭采用
qt_
，隻剩餘版本號開頭采用
qt6_
.
|
|
|
隱藏導入目標開頭采用
Qt::
。相反，需要使用的目標開頭采用
Qt6::
.
|
QT_VISIBILITY_AVAILABLE
|
在 Unix，布爾描述 Qt 庫和插件是否被編譯采用
-fvisibility=hidden
。這意味著僅選中符號被導齣。
|
這些變量能影響由 QT 提供的 CMake 命令。它們可以由工程、工具鏈文件或其它第 3 方包設置。
