Qt 模块的加载采用
find_package
设置各种变量。
注意： 您很少需要直接访问这些变量。像链接到模块的常见任务，应透过每个模块定义的库目标来完成。
例如，
find_package(Qt6 COMPONENTS Widgets)
，当成功时，使以下变量变得可用:
| 变量 | 描述 |
|---|---|
Qt6Widgets_COMPILE_DEFINITIONS
|
要使用的编译定义列表，当针对库构建时。 |
Qt6Widgets_DEFINITIONS
|
要使用的定义列表，当针对库构建时。 |
Qt6Widgets_EXECUTABLE_COMPILE_FLAGS
|
要使用的标志字符串，当针对库构建可执行文件时。 |
Qt6Widgets_FOUND
|
描述是否成功找到模块的布尔。 |
Qt6Widgets_INCLUDE_DIRS
|
要使用的 include (包括) 目录列表，当针对库构建时。 |
Qt6Widgets_LIBRARIES
|
模块导入目标的名称：
Qt5::Widgets
|
Qt6Widgets_PRIVATE_INCLUDE_DIRS
|
要使用的私有 include (包括) 目录列表，当针对库构建并使用私有 Qt API 时。 |
Qt6Widgets_VERSION
|
包含模块版本的字符串。 |
对于找到的所有包采用
find_package
，这些变量的等价物是可用的；它们区分大小写。
此外，还有一些变量与特定包无关，但与 Qt 安装本身相关。
| 变量 | 描述 |
|---|---|
|
|
控制 Qt 版本的整数，
qt_
命令被转发给 Qt 5 和 Qt 6 混合工程。需要将其设为
5
or
6
先前分别
find_package()
调用。
若设为
若未设置，首
|
QT_LIBINFIX
|
保持库名称所用中缀的字符串，当有配置 Qt 采用
-libinfix
.
|
|
|
Hides commands that start with
qt_
, leaving only the versioned ones starting with
qt6_
.
|
|
|
Hides the imported targets starting with
Qt::
. Instead, you need to use the targets starting with
Qt6::
.
|
QT_VISIBILITY_AVAILABLE
|
在 Unix，布尔描述 Qt 库和插件是否被编译采用
-fvisibility=hidden
。这意味着仅选中符号被导出。
