来自这个主题：Ubuntu CMake 添加到CMAKE_MODULE_PATH的路径

我尝试在我的项目中运行 QT5，因为 QT4 不允许我包含 QWebView。

按照上述主题的指南，我现在有一个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 线路切换到 QT5 后，我收到以下错误：

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

所以这告诉我变量QT_USE_FILE现在是一个列表，以前没有。不确定这是否正确，也不确定我能做什么。

谢谢一月

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，您应该使用宏qt5_use_modules而不是QT_USE_FILE和QT_LIBRARIES。

因此，在您的CMakeLists.txt中，您需要删除行：

INCLUDE (${QT_USE_FILE})更改行：

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)

上发：
目前，不推荐使用 qt5_use_modules，应该改用target_link_libraries simpleTree Qt5::Widgets（另请参阅此答案）。
