解决pcl需要的usr/lib/x86_64-linux-gnu/libvtkRenderingPythonTkWidgets.so找不到的问题

问题

在pcl代码编译时clion会出现一个警告

The imported target "vtkRenderingPythonTkWidgets" references the file
   "/usr/lib/x86_64-linux-gnu/libvtkRenderingPythonTkWidgets.so"
but this file does not exist.  Possible reasons include:
* The file was deleted, renamed, or moved to another location.
* An install or uninstall procedure did not complete successfully.
* The installation package was faulty and contained
   "/usr/lib/cmake/vtk-6.2/VTKTargets.cmake"
but not all the files it references.

虽然好像不耽搁使用但很碍眼

解决

check if this file is missing or not
ls -l /usr/lib/python2.7/dist-packages/vtk/libvtkRendering*
python-vtk6 (VTK6.2) is installed, and installed file list:
/usr/lib/python2.7/dist-packages/vtk/libvtkRenderingPythonTkWidgets.x86_64-linux-gnu.so

这个文件就是我们需要的文件，然后建立一个链接接行了。

sudo ln -s /usr/lib/python2.7/dist-
