C++ CMake Qt项目中的链接和UIC顺序

讨论使用cmake构建的Qt5.3.2项目。 这是UIC执行和目标链接库之间的调用顺序问题。。。不幸的是，顺序不是这样的

在这篇文章下面你会发现

1.）my CMakeLists.txt的（仍然有效）摘录部分，以及

2.）命令“cmake”输出的摘录

3.）不使用 生成的标题如“ui_main.h”

如果（在库libqt.a的源代码中）我需要'ui_main.h' 使进程崩溃，但找不到标头。看着 非崩溃生成输出显示了原因：

[..]
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将在生成所需的头文件之前生成libqt.a。 所以我尝试使用类似

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。问题是：如何激励cmake首先运行UIC生成ui头文件，然后编译libqt.a
