CMake Qt 项目中的链接和 UIC 顺序
Linking and UIC order in a CMake Qt project
谈论一个使用 cmake 构建的 Qt 5.3.2 项目。
这是 UIC 执行和 target_link_libraries 之间的调用顺序问题...不幸的是 不是 这个顺序。
在这段文字下方你会发现
1.) 我的 CMakeLists.txt 和
的（仍然有效的）摘录部分
2.) 命令输出的摘录 'cmake .'
3.) 在不使用
生成了 header 类似 'ui_main.h'.
如果（在我的库 libqt.a 中）我需要 'ui_main.h'
make 进程因找不到 header 而崩溃。看着
non-crashing 使输出显示原因：
[..]
Scanning dependencies of target qt
[ 29%] Building CXX object CMakeFiles/qt.dir/home/kochmn/projects/sentinel/src/qt/form_main.cpp.o
[ 35%] Building CXX object CMakeFiles/qt.dir/qt_automoc.cpp.o
Linking CXX static library libqt.a
[..]
[ 52%] Generating ui_main.h
[..]
Make 会在 生成所需的 header 文件之前生成 libqt.a 。
所以我尝试使用像
这样的代码
target_link_libraries(sentinel
${Qt5Widgets_LIBRARIES} ${Qt5Gui_LIBRARIES} ${Qt5Core_LIBRARIES})
add_library(optimization "${DIR_SRC}/optimization/linalg.cpp")
add_library(qt "${DIR_SRC}/qt/form_main.cpp")
target_link_libraries(sentinel qt optimization)
无济于事。问题：我如何激励 cmake first 运行 UIC 生成 ui-header 文件并 then 编译我的 libqt.a?

CMake 生成顺序是根据文件和目标之间的依赖关系计算的。如果您的 qt 库依赖于从 .ui 文件生成的 headers，那么您必须在目标 qt 的输入中添加 ${qt_UI_H} :
QT5_WRAP_UI(qt_UI_H ${qt_UI})
[...]
add_library(qt "${DIR_SRC}/qt/form_main.cpp" ${qt_UI_H})
并且 CMake 通常应该在编译之前对 .ui 文件执行 UIC libqt
顺便说一下，使用 target_link_libraries 仅在 link 时间 设置目标之间的依赖关系。在编译时，正常行为是 "All source files should be found"。在您的情况下，生成了一些 headers，因此将这些 headers 设置为目标的输入可确保生成它们的宏 (QT5_WRAP_UI) 将在编译目标之前执行。
