无法在 cmake 中包含 QT5 的 ui_form 标头

Question

我的 CMakeLists.txt 看起来像：

cmake_minimum_required(VERSION 2.8)
if(CMAKE_BUILD_TYPE STREQUAL Release)
  SET(CMAKE_BUILD_TYPE Release)
  SET (PROJECT_NAME location_recognition)
  message("Release mode")
else()
  SET(CMAKE_BUILD_TYPE Debug)
  SET (PROJECT_NAME location_recognition)
  SET(CMAKE_CXX_FILES "-g -Wall")
  message("Debug mode")

endif()

当我这样做时

cmake .

效果很好。但是当我尝试make 时，它仍然说找不到 ui_forms/*.h 标头并且它失败了。

当我执行 `make VERBOSE=1' 我明白了

因此，不知何故，它要么能够创建 ui_form 标头，要么无法正确链接。 我花了很长时间试验 QT_WRAP_UI 和 QT5_WRAP_UI 但无法解决问题。 为了正确包含 ui_form 标头，我的 CMakeLists.txt 应该进行哪些更改？

Answer 1

您误用了qt5_wrap_ui 宏。根据the documentation，有如下参数

qt5_wrap_ui(outfiles inputfile ... OPTIONS ...)

在你的例子中，这变成：

qt5_wrap_ui(UIS_HDRS
    ui_forms/image_result_matrix.ui
    ui_forms/image_window_widget.ui
    ui_forms/location_recognition.ui
    ui_forms/ui_results_view.ui
)

该命令会将您的项目配置为将 *.ui 文件处理为有效的 C++ ui_XXXX.h，并将其路径保存到名为 UIS_HDRS 的列表中。这允许您将它们用作稍后声明的目标的输入：

add_executable(location_recognition ${SRC} ${UIS_HDRS})

注意：在构建目录${CMAKE_CURRENT_BINARY_DIR}生成ui_XXXX.h文件。
