1 问题描述

        在编译pcl1.8.1时，我先前装过ROS，ROS自带了VTK6.X因此我没装VTK别的版本，在配置cmake的时候发生报错：

CMake Error at /usr/lib/cmake/vtk-6.3/Modules/vtkGUISupportQtWebkit.cmake:14 (find_package):
  Found package configuration file:

    /usr/lib/x86_64-linux-gnu/cmake/Qt5WebKitWidgets/Qt5WebKitWidgetsConfig.cmake

  but it set Qt5WebKitWidgets_FOUND to FALSE so package "Qt5WebKitWidgets" is
  considered to be NOT FOUND.  Reason given by package:

  The following imported targets are referenced, but are missing: Qt5::WebKit

Call Stack (most recent call first):
  /usr/lib/cmake/vtk-6.3/vtkModuleAPI.cmake:45 (include)
  /usr/lib/cmake/vtk-6.3/vtkModuleAPI.cmake:15 (vtk_module_load)
  /usr/lib/cmake/vtk-6.3/vtkModuleAPI.cmake:132 (_vtk_module_config_recurse)
  /usr/lib/cmake/vtk-6.3/VTKConfig.cmake:80 (vtk_module_config)
  CMakeLists.txt:363 (find_package)

        直接再电脑上搜索Qt5WebKitWidgets，打开其项目位置：

        不是conda环境下的哦，别搞错了。

        就是这些。

        打开错误位置的cmake文件，我这里是/usr/lib/x86_64-linux-gnu/cmake/Qt5WebKitWidgets/Qt5WebKitWidgetsConfig.cmake

        

        改称绝对路径。

        接着报错！

        那接着改咯～

        好啦！

        其实我们在上面输入这么一行代码也可以～

set(CMAKE_CURRENT_LIST_DIR "/usr/lib/x86_64-linux-gnu/cmake/Qt5WebKitWidgets")
get_filename_component(PACKAGE_PREFIX_DIR "${CMAKE_CURRENT_LIST_DIR}/../../../../" ABSOLUTE)

# Use original install prefix when loaded through a "/usr move"
# cross-prefix symbolic link such as /lib -> /usr/lib.
get_filename_component(_realCurr "${CMAKE_CURRENT_LIST_DIR}" REALPATH)
get_filename_component(_realOrig "/usr/lib/x86_64-linux-gnu/cmake/Qt5WebKitWidgets" REALPATH)

        set(CMAKE_CURRENT_LIST_DIR "/usr/lib/x86_64-linux-gnu/cmake/Qt5WebKitWidgets")

        开始编译pcl
