c++ - Cmake和QT5-包含仅需一个参数

来自这个话题:
Ubuntu CMake what path to add to CMAKE_MODULE_PATH


我尝试在我的项目中运行QT5，因为QT4不允许我包含QWebView。

遵循上述主题的指南，我现在有了CMakeList.txt:

cmake_minimum_required (VERSION 2.6 FATAL_ERROR)
project (simpleTree)
find_package(Qt5 REQUIRED COMPONENTS Widgets Core)
find_package (VTK REQUIRED)
find_package (PCL 1.8.0 REQUIRED)

include_directories (${PCL_INCLUDE_DIRS})
link_directories (${PCL_LIBRARY_DIRS})
add_definitions (${PCL_DEFINITIONS})

set (project_SOURCES export/exportply.cpp export/writecsv.cpp main.cpp
         controller.cpp
         gui/pclviewer.cpp
         import/importpcd.cpp
         method/SphereFollowing.cpp
         Model/crown.cpp
         Model/Cylinder.cpp
         Model/Segment.cpp
         Model/Tree.cpp)
set (project_HEADERS controller.h
         export/writecsv.h
         export/exportply.h
         gui/pclviewer.h
         import/importpcd.h
         method/SphereFollowing.h
         Model/crown.h
         Model/Cylinder.h
         Model/Segment.h
         Model/Tree.h)
set (project_FORMS   gui/pclviewer.ui)
set (VTK_LIBRARIES vtkRendering vtkGraphics vtkHybrid QVTK)

QT5_WRAP_CPP (project_HEADERS_MOC   ${project_HEADERS})
QT5_WRAP_UI  (project_FORMS_HEADERS ${project_FORMS})

INCLUDE (${QT_USE_FILE})
ADD_DEFINITIONS (${QT_DEFINITIONS})
ADD_EXECUTABLE (simpleTree ${project_SOURCES}
               ${project_FORMS_HEADERS}
               ${project_HEADERS_MOC})

TARGET_LINK_LIBRARIES (simpleTree ${QT_LIBRARIES} ${PCL_LIBRARIES}       ${VTK_LIBRARIES})

将QT4线切换到QT5后，出现以下错误:

CMake Error at CMakeLists.txt:36 (INCLUDE):
include called with wrong number of arguments.  Include only takes one
file.

因此，这告诉我变量QT_USE_FILE现在是一个列表，而不是以前的列表。不知道这是否正确，也不确定我能做什么。

谢谢

最佳答案

CMake Error at CMakeLists.txt:36 (INCLUDE):
include called with wrong number of arguments.  Include only takes one
file.

这意味着变量QT_USE_FILE为空。

在带有Qt5的CMake中，应使用宏qt5_use_modules而不是QT_USE_FILE和QT_LIBRARIES。

因此，在您的CMakeLists.txt中，您需要删除以下行:INCLUDE (${QT_USE_FILE})换线:TARGET_LINK_LIBRARIES (simpleTree ${QT_LIBRARIES} ${PCL_LIBRARIES} ${VTK_LIBRARIES})在:TARGET_LINK_LIBRARIES (simpleTree ${PCL_LIBRARIES} ${VTK_LIBRARIES})并添加行:qt5_use_modules (simpleTree Widgets)
UPD :
目前不推荐使用qt5_use_modules，而应改为使用target_link_libraries simpleTree Qt5::Widgets(另请参见this answer)。
